Your Ultimate Furnace Buying Guide


A new furnace is a big investment for most homeowners. You want to ensure that you choose the right option that fits your family’s needs.

Start by Deciding Your Fuel Type

Furnaces are specifically designed to run on one of four different fuels: electric, heating oil, propane, and natural gas. Both the area that you live in and your operating budget are going to play a large role in the particular type of furnace that you purchase.

The most widely used furnaces across the country are those powered by natural gas and heating oil. Natural gas tends to be the cheapest to run. However, you’ll need to live in an area that has a supply that you can tap onto. Otherwise, heating oil is your next best option. Heating oil tends to burn much hotter, which means a hotter home in less time and less fuel burned to produce the same amount of heat. Unlike natural gas, you’ll need an on-site storage tank for your heating oil.

Propane and electricity are great for areas where natural gas and traditional heating oil aren’t easily accessible. Propane is more expensive to burn than heating oil and natural gas. However, it burns more efficiently than natural gas, so you won’t need as much of it to produce the same amount of heat as natural gas. Just as with heating oil, you’ll need to have an on-site storage tank for your propane. The final option is the electric-powered furnaces. These are going to be the absolute cheapest furnace to purchase. However, since the furnace is powered by electricity, it will be the most expensive to run.

Determine the BTU Capacity That You Need

Once you decide what type of fuel you’ll be burning in your furnace, it’s time to consider what heating capacity it will need to have to comfortably heat your home. Don’t fall victim to the idea that bigger is better. When you opt for a furnace that has way more heating capacity than your home needs, it will cost you more money to run and consistently kick on and off, leaving an uncomfortable environment.

Instead, you want to invest in a furnace that has a heating capacity as near to your desired BTU needs as possible. To figure out your demands, you’ll need to know the square footage of your home. For example, let’s say that your home is 2,000 square feet. Next, you’ll need about 35 BTUs of power for every square foot of space in your Jacksonville, FL, home. After doing the math, it becomes clear that you’re going to need a furnace that has a heating capacity of around 70,000 BTUs.

Choose a Furnace Type

There are three furnace classifications that you have to choose from. These are the single-stage, multi-stage, and modulating. While this may sound a bit confusing a first, these categorizations are simply based on the way that each furnace runs.

The single-stage furnace is by far the most common. It has one flame inside of it that is either fully on or fully off. When this type of system turns on, it will rev up before you feel warm air coming out of your vents. This furnace will run until it’s within a couple of degrees of your temperature setting and then shut off. This furnace is great for meeting your basic heating needs and is the cheapest of the three options.

A step up is the multi-stage, also referred to as “a two-stage furnace.” This type of furnace has been available for about the last 15 years and offers more precise temperature control. Instead of just one flame like the single-stage system, this furnace has two flames inside of it. The smaller flame is intended for mild temperatures while the larger flame is intended for colder temperatures. Multi-stage furnaces are more capable of maintaining constant heat, which means more continuous comfort for your home.

Modulating furnaces are relatively new and boast a micro-managing flame that can automatically adjust up or down depending on your specific heating needs. This type of furnace will run to keep your home within 0.2 degrees of your desired temperature setting. With a modulating furnace, you’ll get even heating that provides maximum comfort for your family and guests. However, you’re going to pay more for a modulating furnace than you are a single or multi-stage furnace.

Consider Energy-efficiency Options

When you invest in a new furnace, you want to take advantage of the energy-efficient options available. The most energy-efficient furnaces on the market are going to come at a higher up-front cost. However, their ongoing operating costs are going to be much cheaper than their less energy-efficient counterparts.

Determining the level of fuel efficiency for any furnace can easily be done by looking at its AFUE value. This stands for “annualized fuel utilization efficiency” and simply reveals how much heat is produced for every dollar that you spend on fuel. So, the higher the AFUE rating on a furnace, the less you’ll spend on fuel to heat your home.

The most energy-efficient options on the market today will have AFUE values in the 90s. The minimum AFUE rating for any furnace is 78. If you’re looking for fuel-efficient options at an affordable price, you’ll want to aim for an AFUE rating of between 80% and 85%. If you’re okay spending more upfront on getting an energy-efficient option, then aim for a furnace with an AFUE rating between 90% and 97%.

A Note on Necessary Supporting Structures

A furnace doesn’t work to heat a house on its own. It needs a support structure in order to transfer the heat it makes throughout your home. If you’re simply replacing an existing furnace, then you already have this support structure of ducting, vents, and so forth. However, if you’re purchasing a furnace for a newly constructed home, then you’ll need to factor in the costs of your supporting structures.

The most vital support structure is your ducting. This is the ventilation system that works to force heat throughout the various rooms in your home. Your ducting is going to be connected to a series of vents. There should be at least two in each room of your home, which are the supply and return vents. These are responsible for circulating air throughout your home.

Lastly, we have the chimney. While you may think of a chimney as only something that you need when you have a fireplace, that’s simply not the case. Chimneys are simply meant to dispel exhaust gases from your furnace as its fuel burns. Unless you opt for purchasing a high-efficiency furnace, you’re going to need a chimney in your home. Realize that it will need to be cleaned once a year as part of your system maintenance.

Why Is My Furnace Rusty?


Is your furnace showing signs of rust? This can be a perplexing issue for many homeowners because, unlike an air conditioner or water heater, heating systems don’t contain water. Despite being less common, furnace rust is still a very real problem and can indicate a number of underlying issues. The best way to diagnose why your furnace is rusting is to have the unit inspected by a licensed HVAC technician. At Reliable Ducts Heating & Cooling, our technicians have many years of experience repairing and replacing rusty furnaces in Jacksonville and the surrounding areas. We’ll send out a specialist right away to inspect your system and determine the cause of the rust.

In the meantime, this article will give you some insight into the most common causes of furnace rust and how to avoid a rusty furnace.

How Common Is Furnace Rust?

A rusty furnace is not as common as a rusty air conditioner, but that doesn’t mean your furnace is safe from rust. A number of factors, from infrequent maintenance to old age, will cause your furnace to rust. Furnace rust is most common on the exterior of the furnace and along the heat exchanger. The danger of rust is that it weakens the underlying metal, which can eventually lead to broken furnace components. While most types of furnace damage only lead to an unpleasantly cold house, some damage can increase the risk of house fires and carbon monoxide leaks.

Furnaces most commonly develop rust when metal components are repeatedly exposed to combustion gases. As the furnace goes through a heating cycle, gas inside of it is heated up before being allowed to cool down. It’s the cool-down stage of this process that generates water vapor. If the vapor isn’t properly vented from the furnace, it will corrode the interior of the furnace, leading to mechanical problems in the future.

Why Do Furnaces Rust?

Excessive humidity: Whenever metal meets humidity, there’s sure to be rust. Atmospheric moisture can weasel its way into your heating system through air ducts. This is especially common after a rainstorm or during humid weather. Once even a small amount of moisture enters the system, it can trigger a chemical reaction with metal that creates rust. If your ducts have breaks or separations in them, they’ll draw in additional moisture, which can do a lot of damage to your furnace.

Combustion vapor: In a gas-powered furnace, the heat exchanger houses combustion gas which cools down into a liquid vapor. Normally, this vapor is vented out of the furnace via an exhaust pipe. But if the pipe is clogged or blocked, the vapor will instead be trapped inside the furnace, causing the metal surface to rust.

Leaky air conditioner: The most common residential HVAC set-up is an air conditioner installed directly above the furnace. This allows both units to share the same blower. Air conditioners generate a lot of moisture during operation, and if the system is properly maintained, that moisture will be safely drained via a drain pan. However, if the drain is clogged or obstructed, the pan will overflow and leak down onto the heater. This issue is especially costly because it requires both the AC and furnace to be repaired.

Different Types of Furnace Rust

Your furnace can develop rust on a range of different surfaces and components. The location of the rust can indicate what’s causing it and how serious of a problem it is. These are the most common types of furnace rust we see:

Surface rust: The exterior shell of the furnace will begin to rust if it’s exposed to a nearby source of moisture. While this isn’t necessarily a major issue, you should confirm that the rust hasn’t spread to the inside of the unit. A certified HVAC technician will do a careful examination of the unit’s interior to look for signs of corrosion and moisture damage.

Heat exchanger: Your furnace’s heat exchanger is an internal component responsible for transferring thermal energy. Even small spots of rust can weaken the metal to the extent that cracks can form. When heat exchangers crack, they can release toxic fumes into the home, including exhaust and carbon monoxide. Since the heat exchanger is hidden inside the furnace, many homeowners don’t realize the component is rusty until it breaks. Luckily, this is exactly the type of damage we look out for during an annual furnace tune-up.

Blocked Flue or Condensate Line: Your furnace contains a flue and drain lines that are used to transport combustion byproducts out of the heating system, including a small amount of moisture. If these components get blocked, the fluid is trapped in the furnace and will begin to corrode nearby components.

Old age: Older furnaces are more likely to have rust than newer units because they’ve been extensively exposed to combustion. If your furnace is more than 15 years old, it’s time to consider a replacement. A new unit will be rust-free and feature greater energy efficiency, which will save you money in the long run. You also don’t have to worry about the many maintenance issues related to furnace rust, including cracked heat exchangers, fires, and carbon monoxide leaks.

Furnaces Are Waterless, So Why Do They Rust?

Furnaces are unique among home appliances in that they use very little water. But that leads us to the question, “why do furnaces rust?” You may be surprised to learn that furnaces do produce a small amount of water vapor. As combustion gas is drawn into the unit’s heat exchanger, the gas cools down and generates vapor. High-efficiency furnaces also contain a second heat exchanger that condenses the vapor to create additional heat.

In well-maintained furnaces, moisture is safely released to avoid becoming trapped. However, if the furnace is clogged, damaged, or poorly maintained, that moisture can get stuck in the system and lead to corrosion. For this reason, it’s important to have an annual furnace tune-up. During a maintenance appointment, a technician will inspect the heat exchanger and ensure the exhaust flue and condensate lines are not clogged.

Furnace Repair or Replacement?

Rust doesn’t go away on its own; the only solutions are to have your furnace repaired or replaced. The best service option depends on the extent of the rust and what components are affected. If your furnace is still relatively young and well-maintained, we’ll probably be able to replace the rusted component. However, if your furnace is older, extensively rusted, or core components are rusted, then replacement is probably the best option.

6 Great Benefits of Regular HVAC Maintenance


With winter right around the corner, it’s an especially important time of year to have your HVAC systems running in the best possible condition. There are multiple ways to care for your appliances and ensure that they give you great results, but providing regular maintenance is perhaps the most important of them all.

By bringing in trained professionals to perform scheduled tune-ups on your heating and air conditioning systems, you’re making an investment in your household that will pay dividends in both the short and long term. We recommend providing each of your HVAC appliances with maintenance at least once a year. By doing so, everyone in your household will be able to enjoy all of the following benefits.

1. More Consistent Climate Control

Of course, your HVAC system has a huge impact on your ability to keep your home comfortable year-round. Regularly scheduled maintenance helps ensure that your furnace and AC will always be able to do their jobs effectively.

When a furnace or air conditioner doesn’t receive regular maintenance tune-ups, it gradually loses its efficiency over time while accumulating excessive wear and tear. This wear makes it more difficult for the appliances to effectively circulate the warm and cool air that they need to provide. In many cases, you will start having to crank the heat or air conditioning up much more than usual to reach a comfortable temperature or wait significantly longer for your home to achieve your desired climate each day.

With regular HVAC maintenance conducted by skilled professionals, you will be able to always retain complete control over the temperature of your household. This way, you and your home’s other residents will enjoy more consistent comfort, even when the weather conditions are extreme.

2. More Money Saved

Providing your heating and air systems with regular professional maintenance can be viewed as a worthwhile investment for your household. When your furnace and air conditioner are properly cared for and maintained regularly, they require less energy to do their jobs effectively. This is because when our skilled HVAC technicians get to work on a tune-up, they’re able to perform the necessary tweaks to make sure that each appliance is running at optimal efficiency. In many cases, you will immediately start to notice that your monthly energy bills have gone down.

In addition to saving money on your monthly bills, regular maintenance will also save you money by greatly lowering the chances of malfunctions and breakdowns. This is true for a couple of reasons. First, because a well-maintained furnace or air conditioner doesn’t have to work quite so hard to do its job, it will accumulate less wear and tear. This means that the appliance’s many components will be less likely to wear out or experience problems.

Secondly, during these routine HVAC tune-ups, your trained technicians will be able to inspect your appliances for any potential issues or breakdowns that may be on the horizon. By finding these issues ahead of time, you will have the opportunity to have them taken care of before they begin to present serious problems for your household.

3. Better Indoor Air Quality

Many people are unaware that their HVAC systems can actually have a significant impact on their indoor air quality. On average, the quality of air indoors tends to contain many more irritants and pollutants than outdoor air, and this can be particularly concerning for anyone who suffers from allergies or respiratory issues. You may not necessarily notice it, but your home contains particles of dust, dirt, and other debris.

If your HVAC systems aren’t maintained regularly, it’s a very real possibility that these irritants are being circulated throughout your home’s air, causing you and the other members of your household to breathe them in regularly. However, when your heating and cooling systems receive regular tune-ups, they are better able to filter out these irritants and prevent them from entering the flow of warm or cool air that is being circulated.

4. Longer Appliance Lifespan

On average, heating and cooling systems will be able to do their jobs effectively for around 10 to 15 years before they need to be replaced. However, this is typically only true of systems that receive regular maintenance. Systems that are not maintained regularly suffer undue wear and tear.

Over time, the excessive wear on your system will lead to more frequent breakdowns and costly repairs. Eventually, a poorly maintained unit will become too costly to fix, and this could occur much sooner than expected. If you want to get the most from your system, regular maintenance is a necessity.

5. A Safer Home

Did you know that when an HVAC system isn’t properly cared for, it can actually present certain dangers for your household? When any fuel-burning appliance is struggling or malfunctioning, it can create the risk of a carbon monoxide leak. If your heating or cooling systems are well-maintained, however, they produce only a minuscule amount of carbon monoxide that can be safely carried out of your home via your ventilation system.

Neglecting maintenance can result in your system producing too much carbon monoxide during operation. Poorly maintained systems are also prone to equipment failures that can lead to carbon monoxide leaks. To keep you and your family safe, a little maintenance will go a long way. Also, regardless of how well you keep up with your HVAC maintenance, you should be sure to always have a working carbon monoxide detector installed in your home.

6. Greater Peace of Mind

Of course, you want to feel safe and comfortable in your home. Investing in HVAC maintenance is one of the best ways to accomplish this goal. After a maintenance visit, you will have peace of mind knowing that all components of your HVAC system are operating optimally. You can also rest assured that your unit will be ready to keep you warm or cool when you need it to. One of the easiest ways to keep up with your regular maintenance is by signing up for a maintenance service agreement with a trusted company like Reliable Ducts Heating & Cooling.

The Basics of the Thermostatic Expansion Valve


The thermostatic expansion valve (TEV or TXV) is a device that is essential in managing refrigerant flow. For this reason, the TXV is useful in refrigeration and air conditioning units and is found next to the evaporator.

Functional Parts of the TXV

The TXV comprises several functional components that work harmoniously to achieve the needed efficiency. The valve body houses all these components; an opening called an orifice controls the refrigerant flow. Additionally, the valve body houses the diaphragm, a flexible material made of metal, and it flexes to apply the needed pressure to the pin.

The needle is another crucial functional component that moves rhythmically up and down to change the opening size in the orifice, thus regulating the refrigerant flow. There is also the spring located within the valve body, and its primary purpose is to counter the pressure exerted by the pin and works in the opposite direction. Furthermore, the valve body has a sensing bulb responsible for detecting the temperature level at the exit point of the evaporator. The reactions of the sensing bulb dictate whether the valve opens or closes.

Pressures Acting Inside the TXV

Typically, three pressures act on the inside of the TEV. The first pressure is exerted at the top area of the TXV and is usually within the power element. As a result of this pressure, the diaphragm moves down, and similarly, the needle also moves down, causing the valve to open.

An increase in the temperature within the evaporator leads to the gas expansion in the feeler bulb, causing the gas pressure in the power element to increase. As a result, the needle moves down, causing the valve to open.

Another pressure operates on the lower side of the diaphragm, resulting from the pressure inside the evaporator. This pressure usually moves the diaphragm upward, closing the valve opening. The third pressure is the spring pressure, which tends to be constant and works to close the valve opening.

The two latter pressures typically work to counteract the pressure at the top area of the diaphragm. Overall, the first pressure aims to open the valve, while the second and third pressure combination tends to close the TXV. As a result, if the valve has to open at a point, the first pressure must be greater than the combined force of the second and third forces.

How the Thermostatic Expansion Valve Works

Typically, the valve works to hold the liquid refrigerant, which has high pressure from making its way into the condenser and regulating the refrigerant flow. The thermostatic expansion valve causes a significant decrease in refrigerant pressure, thus allowing boiling at low temperatures. The boiling is essential as it helps the refrigerant to acquire heat and direct it into the compressor.

Next, the liquid refrigerant, which is under high pressure, is forced through the orifice opening, which significantly causes a reduction in its pressure when it flows past. As the pressure reduces, it causes some of the refrigerant to vaporize while some remains in a liquid state. This process has a similar operation to how a spray bottle nozzle works. When the trigger is pulled, the high-pressurized water inside is ejected through the small opening into a low-pressure external environment. This makes the water comes out as part liquid and part vapor.

The combination of the gas and liquid is injected into the evaporator and gains heat from the pipe. As the refrigerant flows, it is exposed to extreme thermal energy and changes state into a complex gas in the evaporator coil. As a result, the temperature remains constant because of the latent heat.

The refrigerant continues gathering thermal energy, and after the phase change, its temperature begins to increase, resulting in the superheating of the refrigerant vapor. The sensing bulb is alert to these temperature variances to regulate the refrigerant in the main valve body.

Effect of a Rise in the Cooling Load

When there is a significant rise in the cooling load, it results in more refrigerant evaporating within the evaporator. At the exit point of the evaporator, both the superheat and the temperature start to rise.

Since it’s desirable to keep the superheat temperature within correct limits, it’s essential to reduce its high temperature, which is made possible by letting more refrigerant flow. As a result, the pin is pushed downwards and exerts a force on the spring, which adjusts to facilitate the refrigerant to flow past the orifice in the valve body.

The sensing bulb notes the temperature change, and as a result, the refrigerant, usually held in a constrained space within the bulb, evaporates. Because of the limited area where this refrigerant is held, pressure builds up, moving through the capillary tube into the top of the TEV. The diaphragm is pushed down, exerting a downward force on the pin, which in turn exerts pressure on the spring, and it moves to enable the refrigerant to flow in the evaporator.

Next, the valve readjusts to ensure the pressure directed on the diaphragm is more than the pressure produced by the spring. This readjustment allows the desired refrigerant level to make its way through; consequently, the superheat lowers.

Lowering of the Cooling Load

If the cooling load faces a significant decrease, it leads to a decline in the superheat temperature. The sensing bulb detects this change, reducing the flow rate of the refrigerant. The refrigerant that is held in the capillary tube begins to settle back into the bulb, and the valve opening is closed. Eventually, the TXV equalizes, and the desired amount of refrigerant flows through and equalizes with the superheat settings.

Suppose the valve doesn’t respond to the superheat, in that case, it can allow the liquid to pass through into the compressor. The result can be fatal for the compressor since fluids aren’t easily compressible and lead to severe internal compressor damages.

The TEV is crucial in keeping the evaporator active by allowing refrigerant to flow per the cooling load. The valve allows the evaporator to operate as per the requirements and eliminates any possible wastage of evaporator capacity. The valve enables the enclosure air conditioner to work at optimal capacity to deal with the heat loads. For instance, it can function at a greater capacity when the heat load rises.

The TXV, therefore, is a significant part that works with precision to regulate how the refrigerant flows as a response to systematic conditions. For this reason, the TXV has gained popularity in the manufacturing of HVAC systems. This is all you need to be aware of in regards to the primary function of the TEV.

Tips for Saving on Your Heating Bills in Winter


On average, your heating system is responsible for 40% of the energy you consume in your home. You can reduce your utility bills by addressing energy usage by your system. Here are the top tips for saving money on your heating system in the winter.

Address Insulation Problems and Air Leaks
Insulation can boost your home’s comfort and reduce your energy bill. Without insulation, the wall or ceiling will conduct heat to adjacent rooms.

You also require the correct grade of insulation for different parts of your home and your climate. For example, EPA recommends R-values between R30 and R60 for houses in Jacksonville. For the attic, the R-value is between R25 and R38.

The R-value is an indication of the material’s resistance to thermal energy. Without the correct insulation grade, you could be losing up to 50% of the heat from your system. An upgrade of the insulation can reduce your heating bills and extend the life of your equipment.

The type of insulation you need will depend on the availability of space in that room. Fiberglass may require multiple layers to attain the desired R-value. Spray foam, which has a higher insulation rating, is more suitable for smaller rooms with a shortage of space.

An energy audit can help spot areas of your home that have insulation deficiencies or leaks. Leaks around doors or windows can let the air out, leading to high utility bills. You can talk to Reliable Ducts Heating & Cooling in Jacksonville for dependable heating solutions.

Take Advantage of Natural Lighting and Heating
You can manage your heating bills by taking advantage of the energy from the sun. During the day, you can open the windows to let sunlight heat the room. If the day is sunny, keep the blinds, shades, and curtains open.

At night, close the curtains or shades as soon as the sunsets. That way, you’ll be trapping the warm air and, in the process, reduce your heating bills.

You can use heavy curtains, especially if you have air leaks around the window. It can be a temporary solution before you can seal the gaps around windows and doors.

Using ceiling fans in reverse can facilitate the distribution of air around the house. As the fan moves in the counterclockwise direction, it pulls air upwards. You can push a switch at the base of the fan to force it to run in reverse. When you stand beneath it, the draft should be blowing down on you.

You may also want to reconsider the furniture arrangement. Bookshelves and couches could be limiting the airflow and, in turn, forcing your system to overwork. Leave some clearance around the vents to allow air to flow freely in and out of the room.

Lower Thermostat Settings or Use a Programmable Device
According to the Department of Energy, you can save up to 10% of the heating costs by lowering your thermostat. The agency recommends turning down the temperatures by between 7 to 8 degrees for eight hours a day.

You can set different temperatures when you are home during the day and at night while you sleep. For example, the setting when you are awake can be 68 degrees and 60 degrees at night. The colder interiors are more suitable for sleeping, as too much warmth can interrupt your sleep.

You may also reduce temperatures during the cold season when you are away on vacation. Turning down the system can reduce the energy consumption of your home.

However, it is not always a good idea to switch off your systems completely. Heating is necessary to prevent your plumbing from freezing. Additionally, any pets you have will need temperatures close to your regular setting to keep them warm.

When you want to save energy while away, one of the best options is to use a programmable thermostat. You can easily set the system to heat your home half an hour before you return home. When you step through the door, the room will be cozy.

A programmable thermostat has other convenient features to boost your comfort. You can check on your system while on vacation. Some devices can send you a report of your monthly energy consumption. Our technicians at Reliable Heating & Ducts can work with you to find a device suitable for your system.

Consider Zoning for Unused Rooms in Your Home
One way to save energy is to close off any unused areas of your home. If those rooms are always unoccupied, heating them will only waste energy. Ensure the door is closed to trap the heat inside the room.

However, it is not advisable to close off the vents. Air can accumulate and can increase the pressure in the ductwork. Eventually, the air may leak into the unconditioned areas of your home. Your heating system may cycle on and off, trying to keep up with the demands of your home.

Additionally, the design of vents and ductwork is tailored to fit the needs of the building. As a result, components of your furnace may overheat. Your equipment will cycle on and off and will deteriorate faster as a result.

Zoning is the most effective way to lower your utility bills if you have unoccupied rooms. It involves using multiple indoor air handlers connected to an outdoor unit. Heating depends on the needs of each room.

Zoning optimizes comfort in your home by addressing varying temperature needs. It also ensures that all rooms are heated to prevent pipes running behind the wall from freezing.

By zoning parts of the house, you can increase the longevity of the system. Since it only runs when it is necessary, it reduces the rate of deterioration of your equipment. It also strikes a balance between energy consumption and comfort. You can talk to Reliable Ducts Heating & Cooling staff to explore your options in Jacksonville.

Keep Your Furnace Efficient with a Tune-up
The average life of a furnace is between 16 and 20 years. As it starts to age, your system may develop issues such as ignition problems or frequent cycling. A malfunctioning unit works hard to keep the interior warm in winter. As a result, the faulty components will draw more energy in the process.

If your furnace is faulty, a timely repair service will prevent further complications. Ideally, you ought to stick to your annual maintenance routine. Experienced technicians can find fault during the service and replace parts to restore the system’s efficiency.

The frequency of the maintenance service will depend on how often you use the system and the equipment. Once a year is sufficient for a forced-air system. Heat pumps should be services at least once every six months. Busy homes with pets and multiple occupants can schedule a tune-up twice a year for the best results.

If you need trusted heating repair and installation services in Jacksonville, don’t hesitate to call Reliable Ducts Heating & Cooling. We offer a wide range of solutions from indoor air quality to duct cleaning and heat pumps. When you call on our team, you can expect personalized solutions designed to meet your specific needs. For your peace of mind, we offer a 100% guarantee for the service we provide. You can call Reliable Ducts Heating & Cooling’s trusted team today for trusted services in Jacksonville.

Don’t Make These Summer Cooling Mistakes


Most people are looking for ways to get the most out of every dollar and make good decisions about home cooling costs. When you’re looking for ways to cut down on your air conditioner costs, you might turn to friends, family, and neighbors to learn more tricks that could save you a few dollars here or there. But the sad fact is that there are a lot of myths floating around that could end up costing you more than what is necessary. We would like to take some time and help you sort through the misnomers to find better strategies for saving on cooling costs this summer.

Turning Your Air Conditioner Totally Off Only Saves in the Short Term
One of the biggest misconceptions people have about saving on cooling costs is how much it takes to cool a house down from a very high temperature. Lots of people completely turn their air conditioners off when they go to work and come home to an extremely hothouse. Then, they turn the air conditioner back on to cool the temperature down. This seems like a reasonable strategy for cutting costs because you don’t have to pay to keep your house cool when you’re away at work.

However, the amount of energy that your air conditioner has to expend to get it back down to a comfortable temperature is enough to offset any gains you made by turning the air conditioner off all day. To top it off, you have to spend even more on the price of electricity if you’re coming home at a peak time of day. The much better option is to turn your temperature up somewhat higher than what you would set it to if you were at home. This is a good way to save some money rather than paying for cool air that you won’t be around to enjoy. Also, it takes your AC unit longer to cool down your home after it has been off all-day

Closing Doors and Vents to Rooms You Don’t Use Isn’t Actually Helping
You should also be careful about the misnomer about closing the vents and doors to rooms that you’re not using to save on energy costs. This, again, sounds like a genius idea, but the reality is that your HVAC system was set up to work with the entire house. When you close doors and vents, what you end up doing is stopping free airflow throughout the house. This will force your air conditioner to work even harder than it would normally, which will cost more energy and money in the long run.

It Turns Out That Appliances and Electronics Add a Lot of Extra Heat
When you want to cut down on the heat in your home, you should avoid using too many appliances and electronics when it’s hot outside. It’s a myth that things like television sets, clothes dryers, and other household items don’t put out enough energy to matter. The reality is that even a curling iron that’s turned on can often heat up a small bathroom. When you multiply the number of televisions, computers, stereo systems, refrigerators, dishwashers, clothes dryers, and any other appliances that put out energy together, you have a lot of extra heat.

While you obviously can’t unplug your refrigerator and freezer, there are several other steps that you can take to cut down on the amount of heat that various things in your house are producing. For instance, the clothes dryer and dishwasher are two items that put out a lot of heat, but you can use them in the early morning hours when it’s not as hot outside, or you could turn them on before you leave for a few hours so that you don’t have to be around when it’s hot inside. When it comes to cooking with the oven or stovetop, skip it. Either use the barbecue outside or make a meal you can either heat up in the microwave. Or, better yet, make a cold-cut sandwich.

Don’t Fool Yourself Into Thinking That a Lower Thermostat Setting Will Cool Off the House Faster
This might be people’s wishful thinking when they’re frustrated because of the heat, but it’s actually somewhat common for people to turn their thermostats way down to a very cold temperature in an effort to get the house to cool off faster. The reality is that your air conditioner cools off the house at the same rate regardless of whether you set the thermostat to 50 degrees or to 72 degrees. When you turn the thermostat to 50 degrees, you just have to remember to manually turn the air conditioner off.

A better plan of attack is to not let your house get so hot that you have the urge to have it instantly cold. Otherwise, you could have your air conditioner set to turn on about half an hour before you get home so that you can come home to a house that’s already at a pleasant temperature.

Bigger Is Only Better With Some Things
Bigger might be better to some people when it comes to appliances, but it’s just not the case when it comes to air conditioners, which require that you buy the correct size for the square footage of your house. When you buy an air conditioner that’s too big for your space, the air cools too quickly. That might sound like a nice problem to have, but when the air cools down too quickly, the air conditioner shuts off, and it doesn’t have time to pull all of the moisture out of the air. This leaves the house feeling cool but clammy, and most people don’t like this effect. A better option is to buy the right size air conditioner for the size house that you own.

Don’t Think That Doors and Windows Are Your Biggest Problem
It might seem like the majority of the heat that leaks into the house would be around the windows and doors. You may have always been told how important it is to have enough sealings around the edges to keep the house cool and free of humidity. However, you’re going to be surprised to learn that the walls are actually a much larger source of heat transfer than anywhere else in the house. You have pipes and electrical outlets in the house, and if your home is made of wood, there’s a very good chance that you’re losing quite a bit of heat. Brick homes tend to fare better because brick can insulate better than wood. But if you want to cut down on the amount of heat transfer between the inside of your house and the outside, have a professional inspect your home to find all of the key places where you could insulate.

How To Make the Best Use of Your Air Conditioning


Your air conditioner is one of the most important appliances you have at home, especially during sweltering summertime temperatures. And while operating an AC unit seems very simple and straightforward, most homeowners and business owners tend to run theirs inefficiently. Whether it is constantly changing the thermostat settings or placing the compressor unit of their AC in direct sunlight, these habits and decisions not only lead to higher monthly utility bills but also higher AC upkeep costs. To help you run your AC unit more efficiently, here are 12 tips to follow:

1. Avoid Touching Your Thermostat
Adjusting your thermostat to speed up the process of cooling your home is one of the most common fallacies of AC unit operation. Most people are good about maintaining the AC at the recommended 78 degrees. Others might set the temperature higher when the space is unused or lower when temperatures are especially high. Playing around with your thermostat’s setting won’t help with either the rate of cooling or energy consumption. Set your thermostat to the recommended temperature and walk away.

2. Use a Programmable Thermostat
Your AC unit should not be operating during the coolest hours of the day or when nobody’s home. It is unnecessary and adds to your monthly utility bill. In some cases, you might forget to switch it off. It is an honest but costly mistake that can be avoided through the use of a programmable thermostat. With a programmable thermostat, your AC unit can be scheduled to kick on a few minutes before you get home from school or work. This makes sure that you walk into a cool and relaxing haven while also helping you cut down on energy usage.

3. Use Auto Mode
There are two settings on your thermostat that control the air conditioner’s fan: “Auto” and “On.” While there are some benefits to using the “On” setting, opting for the “Auto” setting is typically the better choice. With the fan in Auto mode, air will only blow until the thermostat reaches the desired temperature, and then it will shut off until the next cycle. In addition to reducing the amount of time that the fan is working, the Auto setting also supports better dehumidification by giving moisture from cold cooling coils the time it needs to drip and be drained to the outside. When your AC’s fan is continually running, moisture doesn’t have the chance to drip outside and is instead blown back into the home where it adds to indoor humidity levels.

4. Use a Dehumidifier
During hot days, it is often the humidity that makes the atmosphere unbearable. In addition to cooling your home with your AC, invest in a good dehumidifier to remove the humidity from your home. Some higher-end AC units will have a dehumidifying mode, so you may not have to purchase a separate appliance.

5. Clean or Replace Your AC’s Filters
Your AC’s filters are one of the most important components of the whole system. For reusable filters, experts recommend that you clean them at least once every month and replace them annually. For quick and efficient cleaning, simply vacuum the filter or rinse the filters off with warm soapy water. Disposable filters should typically be replaced every three months.

6. Clean Your AC Fins
Your air conditioner’s fins are the grille-like siding found at the exterior portion of the unit. Similar to filters, the fins help direct airflow. Clogged or bent fins can result in inefficient heat dispersion. Clean the fins using a soft brush such as a toothbrush, or use a fin comb. The latter is a special device to clean and realign bent fins.

7. Clean Your Vents
If you have an air-to-air heat pump unit, you’ll want to regularly check and maintain the vents for efficient cooling. Vents that are blocked by dirt and debris or have structural damage can affect airflow and your AC’s ability to get rid of hot air. If you do not wish to regularly maintain your AC’s vents, consider switching to a ductless system. Each type of heat pump has its own pros and cons that you will want to talk about with a qualified HVAC technician.

8. Use Blinds
Of course, we all know that natural light can be great for lowering your lighting costs by keeping rooms well-lit without having to use electricity. In terms of temperature regulation, however, natural light can account for roughly 25% of the heat indoors. Keep the blinds and curtains closed in empty rooms, especially during the day and in rooms that are facing east or west.

9. Use Fans
During the cooler hours of the day, such as nighttime when the heat starts to taper off, you can turn your thermostat up a few degrees and use ceiling or tower fans instead of the AC to cool your home. The energy consumed by fans is significantly lower than that of an AC unit, especially for older AC units that are not ENERGY STAR-certified. You can also use fans in a support capacity to help your AC unit move cold air around larger spaces.

10. Eliminate Hot Air
Exhaust fans are commonly found in bathrooms and kitchen spaces. You can use them to expel hot air from the premises. In addition to hot air coming from outside, certain domestic activities, including running your washer, dryer or dishwasher, can generate heat that lingers inside your home. Cooking is another common activity that generates a significant amount of heat. If your home does not have an exhaust fan, you can use a tower fan in the kitchen while you cook.

11. Avoid Cooking or Washing at Noon
Perhaps the easiest way to eliminate hot air generated by the domestic activities listed above is to reschedule them to the cooler hours of the day. Put off dishwashing or cooking until at least late afternoon or early morning the next day. Roasting a whole chicken in a 400-degree oven while it is a sunny 90 degrees outside forces your AC unit to work harder to cool the place down.

12. Keep Your AC Unit Out of Direct Sunlight
The recommended location of a central AC unit is on the north section of your property. Unfortunately, this isn’t always an available option. You can instead make use of landscaping techniques to provide cover for your AC’s compressor unit. Not only does it give your AC unit some shade, but planting shrubs and trees around your home also helps cool your home naturally.

How To Reset Air Conditioning Unit


The worst thing that can happen to any homeowner is the breakdown of their air conditioning unit in the middle of summer, especially when you are not financially prepared. Learning how to reset your AC will help you reboot it to correct glitches. Note that ACs contain a protection circuit breaker meant to prevent fire and explosion. In case of a blackout, your unit may fail to kick on immediately once power gets restored. In such a case, you need to reboot the system to restore its functionality. Also, if you set your AC to cool but it fails to blow in cool air, rebooting can sometimes help fix such an issue. Here are some ways you can reset your AC.

1. Use the Reset Button
The easiest way to reset an AC is by using the reset button. Most units have one, usually a small red button located on or around the AC body. It’s tiny to prevent it from being accidentally activated. If you can’t find it, read through the manufacturer’s manual, or do a quick online search for your brand. Once you find the button, long-press it for around three seconds, and observe whether your AC responds. If it doesn’t, check if there is power, then press the reset button once again for three more seconds. The AC should respond by beeping three times before it kicks on. If you don’t find the reset button, you may want to try another method.

2. Reset the AC Via the Power Point
If your unit doesn’t have a reset button, you will need to reboot it manually. However, this might take longer for your system to get back to work. Locate the power point. For a portable, window, or wall split system, it’s usually at the indoor unit. First, turn the power off for safety purposes. Next, remove the power cord from the electrical panel to ensure that the AC isn’t receiving any power. Leave it disconnected for about 20 to 30 minutes to allow all the charge to dissipate.

Once the time elapses, plug the AC to back to power, turn it on and see how it functions. If it still fails to work, unplug it again and plug in another appliance to the power point. If the device works, then the power point isn’t faulty, so try out another restarting method. However, if the device doesn’t work, then the power point has a problem, and you need to call a technician to fix it.

3. Use the Isolation Switch
Look for the isolation switch located by the outdoor unit. It has a shape similar to an inverted letter V with an on and off position. For older models, the isolation switch might be near the indoor unit. It looks like an ordinary light switch, so you will need to confirm this from the manufacturer’s manual. The primary role of the isolator is to disconnect the power supply to the unit when it detects unusual electric currents to reduce the risk of electrical problems.

Turn the isolator to the off position, then leave it for about 30 minutes. This is to allow the AC to reset and troubleshoot mechanical issues. After 30 minutes, turn the isolator on, switch on the AC and observe if it’s working as expected. If it still doesn’t work, you can try out the next method.

4. Reset the AC Via the Circuit Breaker
First, turn the AC’s thermostat to the off position, look for the shut-off button located on the unit and turn it off for safety purposes. Now find the circuit breaker box, usually in the basement, crawl spaces, or closet. Open the switchboard’s door to gain access. Your circuit breaker should have clear labels of each item on the circuit control, so look at it carefully. Look for the breaker linked to your AC and flip it to the off position. Wait for about 30 minutes, then turn the circuit breaker back on.

Note that some models have fuses. Once you open the switchboard door, you might need to remove a second cover to access the fuse. To reset the AC, pull out the fuse and fit it back after some time. Replace a damaged fuse with a new one, but if it’s still in working condition, you can refit it. Once you reinstall the fuse or turn the safety switch back on, set the thermostat to cool, turn your AC on, wait for it to cool, and observe whether it’s working well.

5. Seek Professional Assistance
After trying out all the solutions above and your AC still fails to restart, check if there is a power supply, and then call a professional to troubleshoot and fix the issue. Also, if your AC completely stops working after restarting it, have a professional examine it. You should never attempt to reboot the AC if it frequently malfunctions. This indicates the presence of an underlying issue that needs professional assessment.

If your AC cools your house slowly and it’s old, you don’t need to restart it. Instead, call a technician to service it, and if it still doesn’t work as expected, it might be time to replace it.

Additionally, if the breaker keeps tripping and you need to restart your AC multiple times, there is an issue that needs immediate attention. Continuing to run the AC at such a state will cause more damage to the interior components calling for expensive repairs and replacements.

You should never attempt to restart the AC if the switchboard panel has exposed wires. This will only put your safety and that of your loved ones at risk. Exposed wires can cause shock, electrocution, and even a fire breakout. Also, if you restart the unit, you might end up causing permanent damage, and you will replace the AC sooner than expected. In such a case, call a qualified technician immediately to address the issue.

Are You Having Trouble Restarting Your AC? Seek Professional Help
When your unit stops working, you shouldn’t just rush to call a technician while you can try resolving the issue by simply resetting. Restarting your AC can help solve minor mechanical problems and get your unit back to work. However, resetting your AC isn’t always the solution. If the above tricks don’t work, you could be dealing with a clogged air filter, low refrigerant level, frozen evaporator coils, fan problems, or leaking duct. In such a case, you need to call a professional to check the root of the problem. Regular AC maintenance will also help prevent such issues. During tune-ups, the technician will change or clean the filters, clean and inspect the coils, lubricate the moving parts, recharge the refrigerant and fix any loose electrical connections to ensure that the AC runs smoothly. They can also easily detect minor problems and resolve them before they escalate into significant issues.

Does Humidity Affect My Air Conditioner?


High levels of humidity indoors are not only uncomfortable but can damage valuables in your home. Additionally, high moisture levels will impact your air conditioner’s ability to regulate temperatures. In regions where it is hot and humid, your AC will struggle to maintain comfort. This article will explore the different ways humidity affects your AC and some practical solutions for addressing humidity levels.

How Humidity Levels Affects Comfort and AC Efficiency
The primary role of an air conditioner is to draw out hot, stuffy air and replace it with cold and fresh draught. But your HVAC unit has another function, which is to regulate humidity and keep the levels low. When the humidity level rises dramatically, most systems cannot handle the excess moisture in the interior.

Even when the AC is at its optimum performance, considerable amounts of vapor can affect its function. When it’s humid, the air feels hotter and muggier than it is. As a result, there is a temptation to turn up the air conditioning to raise the comfort levels in your home.

The ideal humidity levels are typically between 30% and 60%. Above 60%, and the atmosphere is moist and damp. The concentration of vapor can be high enough that your skin starts to feel clammy. Another critical sign is a musty or pungent smell coming from parts of your home. It is an indication that microbial growth is beginning to spread due to excess moisture.

When humidity is below 30%, it can also have adverse effects on your valuables, health, and comfort. It can cause itching and skin irritation. Additionally, dry air damages valuables made of wood, forcing them to crack and weaken. For optimum comfort, the challenge is to keep humidity levels between 30% and 60%. In such situations, we recommend using a humidifier.

Humidity Levels and AC Sizing Factors
It is a myth that you need a high-capacity air conditioner to keep your home cozy through the summer. Accurate sizing is crucial for optimizing the efficiency of your unit. An oversize system will not only raise your utility bills but will also affect your home’s comfort.

When AC is oversize, it will cycle at a frequency higher than a regular cooling system. It will keep switching on and off to prevent overcooling the room. As such, your equipment does not run enough to remove excess moisture from your home’s interior.

For that reason, it is essential to have an HVAC system that is the correct size of the interior. It will also be challenging for an undersize or aging cooling unit to keep humidity levels in check.

Ventilation System Design and Impact on Humidity
Another factor that can impact humidity levels is the type of air conditioner you use in your home. A single-speed air conditioner will have the same effect as an oversize HVAC unit. It will keep running until it reaches the desired temperature levels and then switches off until temperatures rise again.

A variable-speed motor can run at varying speeds, as the name suggests. With variable speed systems, the temperature regulation is gradual and slower. Your equipment has a better chance of removing humidity in the air than a conventional single-speed AC.

A variable-speed AC unit works best when you pair it with Smart systems. You can change the settings of a programmable thermostat to ensure temperature regulation is accurate. Not only will you be reducing your equipment’s energy consumption, but also manage the levels of moisture in the building.

Poor ventilation design allows negative air pressure to accumulate inside the ductwork. The AC draws too much air into the ducts, creating negative pressure. When the air is very moist outside, it will pull the vapor into the interior, raising humidity levels.

Maintaining Healthy Humidity Levels
When indoor moisture levels are high, your body struggles to remain cool. That is because vapor makes it harder for sweat on your skin to evaporate. It is the evaporation process that absorbs heat from your body. As a result, you have a higher risk of heatstroke due to high humidity levels.

Indoor moisture levels can be higher than in the outdoors. That is often due to air finding its way into your home through crawlspaces or openings on the wall. Activities taking place in your home can also raise the humidity to unhealthy levels. You can optimize home comfort by doing some tasks outdoors or taking practical precautions.

Showering, cooking, and hanging clothes to hang outside are some activities that could raise moisture levels. If you must carry out these tasks indoors, consider using an exhaust fan. Exhaust fans are used in bathrooms and kitchens or rooms where humidity is likely to be a problem.

Another way to control moisture is to encourage circulation around the house. Leave doors between rooms open to allow movement of air across spaces. That way, heat moves to cold surfaces preventing condensation and the accumulation of moisture.

Moisture Problems and Weatherization
Moisture issues tend to vary depending on your location and climate. In Florida, the air is often hot and humid, as opposed to hot and dry, in the southwest regions. The solutions to these humidity problems must consider the climates and their implications.

For example, using a single-speed or oversize air conditioner could worsen the moisture problems in places like Florida. You will be tempted to raise the thermostat settings to keep your home cooler. But you’ll only overwork your AC and increase energy consumption.

The design of your cooling system is, therefore, most crucial in maintaining healthy humidity levels. At Reliable Ducts Heating & Cooling, we offer exceptional air quality services in Jacksonville. Our acclaimed team can carry out ventilation testing and duct cleaning. Our humidity control solutions will keep your Jacksonville home cozy even in extreme weather.

When to Use Dehumidifiers
When it is hot and muggy in Florida, you can reduce moisture levels by using a dehumidifier. A dehumidifier removes moisture from the indoors, preventing microbial growth and musty odors. You can use it when you experience discomfort, but how you utilize it will impact energy savings.

The best time to run the dehumidification system is before humidity accumulates in the house. If moisture accumulates, occupants will feel like the interior is hotter than it is. So you can run it as soon as you notice humidity levels rising.

Ideally, the dehumidifier should run for about 12 hours a day when moisture levels are in the upper range. Home comfort specialists consider that to be the best way to eliminate humidity at optimum energy efficiency.

The high levels of humidity in your home could also be from indoor activities. In such situations, it is advisable to determine the precise moisture levels using a hygrometer. Reliable Ducts Heating & Cooling will be glad to assess your Jacksonville home for humidity and energy efficiency.

We provide indoor air quality solutions such as ventilation testing, duct cleaning, UV light, and humidity control. As a family-owned company, we have a reputation for offering customer-focused services. Our range of services includes AC installation, maintenance, and repairs. Our services come with a 100% guarantee. You can count on Reliable Ducts Heating & Cooling for unbeatable solutions in Jacksonville.

Why Is My Air Conditioner Making Noises?


Most people love to spend time in a cool air-conditioned house when summer hits. However, when the AC unit starts making some strange noises, it could make your home less comfortable. Ignoring such signs can cause major issues in your cooling system, resulting in expensive future repairs. The sooner you can spot the cause of the noises and fix it, the better. Beware of the following noises from your air conditioner.

1. Banging or Clanging Noises

Any time you hear clanging sounds from the outdoor unit, it means that something is disrupting the fan’s operations. It could also be a sign that the AC unit has some broken components. Due to normal wear and tear, various compressor parts may become loose, creating loud banging sounds. Unfortunately, you might need to get a new compressor.

Other times the blower motor can get out of balance, hitting other components. Such issues can worsen when ignored, so immediately turn off the system and call a professional to check the issue before it damages other parts.

2. High-Pitch Screeching or Screaming Noise

If your AC unit produces loud screaming or screeching noises, it could be having issues with the compressor or fan motor. If the unit kicks on and you immediately hear the noises, the compressor is likely operating at very high pressure. In this case, you need to shut off your system and immediately call a professional. You might need to replace the compressor or the entire appliance. On the other hand, if the noise is present the entire time while running the air conditioner, you could have a loose fan motor. Again, contact an experienced HVAC technician to replace it.

3. Rattling Noises

Rattling sounds indicate a problem with the blower or assembly motor. This happens when a part of the assembly motor or blower becomes loose and begins to toss around inside the outdoor condenser unit. Turn off the power, and then inspect the condenser unit for any loose parts you can fasten. Additionally, your AC unit may produce rattling noises when clogged with twigs or leaves. Clean the area around the outdoor unit.

4. Unusual Hissing or Bubbling Noise

Hissing sounds from the indoor unit are signs of a refrigerant leak. During normal operation, the refrigerant runs in a closed loop. When these capillary tubes corrode or wear off, they create holes where the refrigerant escapes at a high pressure, producing hissing sounds.

Shut off the system immediately and call a professional. Note that a refrigerant leak can reduce the system’s efficiency and cause some health risks to your family.

If the hissing sounds come from above the ceiling or under the floor, it could be due to leaky ductwork. This will not only cause annoying noises but also waste energy. Depending on where the leak is, you can fix it yourself using duct tape, or you may seek professional assistance.

5. Loud Humming Sounds

A neglected fan can cause humming sounds. Your air conditioner requires constant maintenance to clean its components and keep them in working conditions. If one of the blades in the fan motor bends, it can also cause humming sounds. Sometimes it’s due to electrical problems that need immediate attention. Other times the AC unit produces humming noises due to loose wiring.

6. Loud Clicking Sound

A consistent clicking sound signifies a defective thermostat, contractor, or controls. It’s a good idea that you leave electrical issues to professionals. You can sometimes hear loud clicking noises when an object finds its way into the blower fan, so it continuously hits against the fan as it runs.

7. Buzzing Noise From the Outdoor Unit

A buzzing sound from your air conditioner means that you could be having electrical issues. It mainly happens due to loose wiring or issues with the fan motor or circuit breaker. For the circuit breaker, the cause of the problem is usually dirty air filters or debris around the unit. Although it might seem like a simple issue to fix, electrical problems are hazardous and require a professional approach.

Other causes of buzzing noises include a dirty condenser coil, an imbalanced blower, a loose outdoor fan motor, copper lines rubbing against obstacles, and refrigerant leaks.

8. Unusual Whirring Sounds

Whirring sounds in an air conditioner usually appear due to mechanical problems in the indoor or outdoor fans. When the fan blades become loose, they produce some helicopter-like whirring sounds. The noises may also result from broken belts, and you need to call a professional to assist you with this.

Additionally, this can happen when a piece of paper or other debris gets trapped in the blower motor, causing rapid whirling sounds. If you can, remove the obstruction. Be sure to also keep the area around the unit tidy and discourage your kids from playing too close to it.

9. Pulsating Noises From the Outdoor Unit

A little pulsing noise from your air conditioner shouldn’t raise concerns since this happens with the unit’s normal operations. However, if the outdoor unit makes excessive pulsating sounds, such that you can hear them inside the house, you need to have the unit inspected. It’s a sign that there’s a loose part inside the appliance, like the fan motor, which may need replacement.

Other times this happens when the refrigerant line comes into contact with walls as it passes through. Contact a professional to move the refrigerant lines away from the walls and add insulation to stop the pulsing.

10. Whistling Noises

Whining or whistling noises from your AC unit signifies problems with airflow. It can happen if the ductwork is incompatible with your HVAC unit. Also, if the ductwork is too narrow for the air blowing through the appliance, it can cause whining sounds. This can happen when you have cracked ducts or clogged filters too. You can resolve this by cleaning or changing the filter, or you can call a professional to seal the ductwork.

Additionally, if you have an older unit with multiple repairs or replacements, it can produce whistling sounds if the parts fail to fit correctly.

11. Cracking or Popping Noises

If you notice constant cracking noises from your air conditioner, ice could be forming inside your unit. This happens when you set the temperature too low or when the system fails to drain appropriately. You can resolve this by setting your thermostat to a higher temperature. If the sounds persist, have a professional technician assess the issue. Additionally, pull out the drain pan, empty it, and clean it to prevent backup of cold water that can freeze in the air conditioner.

Summing Up

Investigate the cause of noises in your AC unit before calling a technician, as you may be able to resolve some issues with simple adjustments. If the problem persists or involves complex tasks like electrical faults or compressor replacement, contact a professional. Note that regular air conditioning maintenance can help prevent noise occurrence. An HVAC technician can identify problems early on and fix them to eliminate disturbing noises.
