The Importance of a Thermostatic Expansion Valve


A thermostatic expansion valve is a useful piece of equipment that regulates pressure and temperature in a hydronic heating system. It makes the system safer and more efficient by reducing the backflow into the boiler and preventing damage to sensitive components.

At Reliable Ducts Heating & Cooling, we offer TEV services such as installations, repairs, maintenance, and replacements. When your TEV needs attention, you can count on us to provide top-notch inspections and diagnostics. Whether you’re looking for a new TEV for your system or you simply need a few repairs, we’re the ones to call.

What Do Thermostatic Expansion Valves Do?

TEVs are commonly used to control hot water and steam. In simple terms, TEVs are valves with multiple functions. They act as a check valve, shut-off valve, pressure controller, and thermostat in one device.

Check valves prevent backflow, while shut-off valves allow you to turn the hot water on or off. Pressure controllers reduce pressure to prevent damage to equipment. They also reduce pressure in the event of high pressure to prevent blowback.

Thermostats use a heating element and probe to measure the temperature and turn the valve on or off accordingly. The thermostatic expansion valve is most commonly used with hydronic heating systems such as hot water heaters or boilers.

When using gas as a heat source, this device can be replaced with a manual or automatic gas control valve. In other words, it’s not mandatory but recommended for the optimal performance of your system.

How Does a Thermostatic Expansion Valve Work

A TEV is used to control pressure and temperature in a hydronic heating system by regulating the flow of water or steam to a boiler. It has two main components: a nozzle and a thermostat. The nozzle is installed in the system’s water supply line, and the thermostat is installed in the water return line.

The water enters the nozzle, and the pressure of the system pushes the water through the nozzle and into the return line. The hot water is then delivered to the circulation pump, and the return line is sent back to the boiler. As the water travels to the boiler, it is heated by the boiler’s water.

The nozzle acts as a restriction in the line that allows the water to enter the return line under a predetermined amount of pressure. The thermostat in the return line acts as a pressure controller and temperature sensor. The boiler’s temperature is also monitored.

Why Are Thermostatic Expansion Valves Important?

They are important for a number of reasons. They help prevent low and high water pressures, which can cause damage to equipment. TEVs prevent blowback, which happens when the water pressure exceeds 100 pounds per square inch in residential systems.

They also help prevent scalding by regulating the temperature of the water. The pressure in a hydronic heating system is controlled by the amount of flow to the boiler. The more flow there is, the higher the pressure.

If you have low water pressure, it’s usually due to the boiler not receiving enough flow. In this case, the water stays in the system too long. If the pressure exceeds 100 psi, then there is possibly an issue with the system.

Tev Maintenance

A trained professional can help you maintain the functionality of your TEV. An HVAC technician can clean the nozzle once a year by removing it from the line and running water through it. This will allow a slow and steady flow of water through the nozzle, which will prevent erosion.

You should also have a technician replace the nozzle every five years or when there are signs of wear and tear. Your technician should make sure to replace the existing nozzle with exactly the same model.

It’s important to know that if the nozzle is not closing properly, it might also be a sign that your thermostat needs replacement.

Thermostat Replacement

If the nozzle is working just fine, but you still need to replace the thermostat, a technician can get to the root of the problem by shutting off the system. Then, he or she will remove the old thermostat and check the gauge on the side if there is one.

Next, the technician will install the new thermostat and place it in the return line where the old one was. The new thermostat should be the same model and have the same settings as the old one.

If you notice that the new thermostat isn’t working as efficiently as the old one, it could be due to the type of piping being used. The new type of piping might restrict the flow too much.

Maintaining Your System

When a TEV needs replacement, it’s important to handle this job right away. If a worn-out TEV remains in place for too long, it could compromise the boiler and thermostat, necessitating extensive repairs. A repair technician from Reliable Ducts Heating & Cooling can perform yearly inspections to ensure that your TEV is in proper working order.

Under normal conditions, you shouldn’t need to interact with your system’s TEV. It will continue working without your interaction for many years, although regular inspections and maintenance will extend its lifespan considerably. TEV maintenance is straightforward and affordable. At Reliable Ducts Heating & Cooling, we aim to make TEV repairs as fast and efficient as possible.

11 Benefits That Come With an HVAC Maintenance Plan


HVAC maintenance plays a huge role in ensuring your system has a long life span and runs efficiently. Several tasks are done while maintaining your equipment to protect your home and ensure it keeps your family comfortable all year long.

Homeowners often forget to have their HVAC system serviced, thus necessitating a maintenance plan. Routine maintenance involves your technician inspecting, testing, and servicing critical components in your system to reduce wear and ensure efficiency. It is easy to forget about scheduling heating and cooling tune-ups as we rarely think about our system until it starts malfunctioning. Neglecting your HVAC system can have grave consequences which affect your home as well as your equipment. A maintenance plan ensures you stay on top of your system’s needs by having scheduled tune-ups. Our experts at Reliable Ducts Heating and Cooling discuss why investing in a maintenance plan has its share of benefits.

1. Improved Energy Efficiency

An HVAC system that is rarely maintained must work harder to cool or heat your home properly. With your system working harder, not only does this cause wear that reduces the lifespan of your equipment, but it also increases energy bills due since the system has to use more energy to get the job done. A maintenance plan is important as it ensures your system is frequently serviced, improving its efficiency and thus ensuring your energy bills remain as low as possible. Homeowners may put off servicing their units due to the cost; however, having your unit regularly maintained saves you money in the long run since your unit will run efficiently, and there is a reduced chance of unexpected repairs.

2. Pro-Longed Lifespan

Heating and cooling systems are an investment for the comfort of your home. Like every investment, the main goal is to get the most from it. A well-maintained system should last for an average of 15 to 20 years. As your HVAC system ages, it is prone to wear and tear. Therefore, constantly replacing your unit might become a tedious and expensive ordeal, which can be avoided by servicing your equipment.

Neglecting your equipment means it has to work harder, thus straining your air conditioner and reducing its lifespan. Having scheduled tune-ups improve its reliability and performance and ensures you are not forced to retire your conditioner earlier than you intended.

3. Prevent Unexpected Breakdowns

Imagine your air conditioner malfunctioning deep into summer when you need it most. Breakdowns affect the comfort of your home and may require expensive repairs. A maintenance plan can help to prevent unexpected breakdowns. With a maintenance plan, your unit is inspected frequently by a professional. An inspection enables the technician to find pre-existing problems and fix them before the problem causes a malfunction or becomes too expensive to repair. Having enrolled in a maintenance plan also ensures the cost of repairs is lowered.

4. Reduced Maintenance Costs

The main reason why most homeowners fear maintaining their air conditioners is the cost. With your finances already stretched thin, you may find it hard paying for a maintenance check for your AC. However, with a maintenance plan, you receive huge discounts on components of your system. You also get significant savings on repairs which are guaranteed to improve your equipment. Regular maintenance catches small issues that are relatively cheap to fix. Lack of maintenance means you won’t catch these issues until they snowball into major repairs that are much more expensive.

5. Prioritized services

Despite having discounted prices for maintenance and repairs, a maintenance plan member also gets prioritized services. Your needs will always come before those who don’t have a plan. Investing in a maintenance program has advantages, as this prioritization can come in handy when you require immediate assistance for your heating, ventilation, and air conditioning system.

6. Know Your System Is Ready

Servicing your system can save you a lot of money and trouble. When your system is inspected, small issues can be caught and repaired before they become hazardous to your equipment and home. These regular tune-ups ensure your air conditioner is always ready and doesn’t break down or malfunction when needed. Investing in a maintenance plan is the best way to ensure your heating and cooling system is always ready, thus giving you peace of mind in your home.

7. No Need For Reminders

A major concern with HVAC maintenance is that you forget about scheduling the maintenance. People having busy days will likely forget about your system, especially if it functions as it should. Care of your equipment is crucial, especially if you want to save on bills and get a long life of service from the HVAC system. Luckily, maintenance plans come in handy because your HVAC service plan will keep track of your service history and contact you to make sure you schedule a tune-up when necessary. This is very beneficial as it lets you have peace of mind and the ability to focus on your other responsibilities without worrying about your conditioner. We can say that forgetting to schedule a tune-up is a thing of the past when you invest in an HVAC maintenance plan.

8. Improved Indoor Air Quality

The air quality inside your home is important, especially if your family suffers from respiratory conditions like asthma. If your system has been running without maintenance, the air quality inside your home will be affected due to the various contaminants the air may carry. During servicing, your technicians should inspect and clean the fan coils, motors, and other parts to remove dust and other allergens that may have collected. Your air filters should also be checked, cleaned, or replaced if dirt has accumulated.

9. Familiarizing With Your HVAC System

Another advantage of having a maintenance plan is that the same experts work on your system each time you require a service. This allows the technicians to familiarize themselves with your unit. Having one company doing your maintenance ensures your system is given dedicated care.

10. Maintaining Your Warranty Coverage

Sometimes regularly servicing your HVAC system is a requirement to avoid nullifying your warranty, especially if your HVAC system is new or still under warranty. If your manufacturer learns you were not maintaining your unit when the problems started, they can void your warranty, costing you more money. Registering in a maintenance plan can be crucial in upholding your warranty if you require it in the future.

11. Reduced Noise

When your system is properly maintained by a professional, they will clean and lubricate all moving parts. This helps the system to work with a lot less strain which results in less noise. Additionally, if your system seems to be louder than normal, a routine inspection can find and repair the issue, returning your system to quiet operation.

How Can I Cool a Home That Doesn’t Have Ducts?


Summers in Jacksonville can be brutal. For most people, this is the time to crank up the air conditioning and enjoy time indoors. However, if your home doesn’t currently have an air conditioner, keeping your home cool isn’t as simple as just turning back the thermostat. Fortunately, if you need to stay cool this summer, there are several great options available, even if your home doesn’t have any existing ductwork from a previous system. Here are the systems that the pros at Reliable Ducts Heating & Cooling recommend to help beat the heat on the hottest days of the summer

Adding Ducts

If you don’t have ductwork in your Jacksonville home, there is always the option of adding ductwork. However, most people don’t choose this option because adding ducts to a home that’s already been built can be disruptive, time-consuming, and expensive. To get the ducts where they need to be, you may have to make significant changes to the structure of your home. Plus, you’ll need to find a central location for the main system components. If you choose this option, you may need to opt for flexible ducts, which tend not to be as durable or energy efficient as their rigid counterparts. While it’s possible to add ducts to an existing home, the good news is that there are other options that are much less expensive and disruptive.

Window Units

Another potential option for cooling your home is window-unit air conditioners. The big problem with this approach is that you have to take up window space, thus blocking natural light from coming into your home. Plus, it is usually difficult to properly insulate the area around the air conditioning units. Another big drawback of these units is that you have to remove and re-install them every year so that they don’t allow cold air in during the winter. On top of that, window units tend to be fairly inefficient and noisy, not to mention that they’re unattractive. One final drawback of depending only on window units is that you can’t cool any rooms that don’t have windows, such as a basement or attic.

Portable Air Conditioners

For temporary cooling, a portable air conditioner can do an adequate job. These units only require a small duct to go through a window, making them less obtrusive than window units. Plus, since they’re portable, you can technically move them from room to room to cool your home as you move around. However, many homeowners find portable air conditioners to be inefficient, making them unsuitable for anything more than a small room. Plus, portable units take up valuable floor space that you might need for storing other items.

The Best Option: Ductless Mini-Split Systems

Of all the ductless options available to homeowners, ductless mini-split systems are the option that Reliable Ducts Heating & Cooling recommends most often. That’s because these systems are efficient, quick to install, look great, and provide both cooling and heating capabilities. You can install mini-split systems in any room in your home, including basements, because the only part of the system that goes from inside to outside is the refrigerant line. The durability and versatility of mini-split systems also make them great options for garages and workshops.

Great Efficiency

As with any targeted cooling system, mini-split systems are efficient largely because you can choose which rooms in your home to cool. This means that you aren’t paying to cool your entire home at once, a much less efficient and more expensive way of maintaining comfort. Since mini-split systems are only designed to cool a single room, they can be much smaller than their whole-home counterparts. In other words, they require much less energy to operate. An added benefit of mini-split systems is that they are air-source heat pumps. This technology pumps heat from the outside air into your home, which is far more efficient than conventional heating methods. Therefore, if you are using your mini-split system to heat your home in the winter, you can enjoy year-round efficiency.

Great Ease of Use

Another feature that we at Reliable Ducts Heating & Cooling love about ductless mini-split systems is that they are incredibly easy to use. All you need to control the temperature in your home is a simple remote control. You can select fan speeds, heating and cooling levels, and then you can set the desired temperature without walking across the room to a thermostat. This makes mini-split systems ideal for individuals who aren’t tech-savvy and may struggle with using a typical thermostat. Plus, their small size and simple construction make it easy to clean these systems in order to maintain their efficiency. A simple dusting of the outside of the indoor unit is the majority of the maintenance that you’ll need to do.

Fast Installation

Unlike the mess and chaos of installing ductwork in your home, mini-split systems are fast and easy to install. Reliable Ducts Heating & Cooling can typically install a mini-split system in just a few hours, meaning you can enjoy the comfort you deserve more quickly. Plus, with just one or two holes to drill in walls, there will be very little mess made and no extra dust released into your home’s indoor air. Once installed, a mini-split system’s indoor unit is unobtrusive and can blend in with any decor since the unit is mounted high on a wall and out of the way.

Cooling for Multiple Rooms

A great feature of a mini-split system is that you can use multiple units to provide cooling for multiple rooms. In many cases, you can tie more than one indoor unit into a single outdoor unit, saving space, wiring, and energy. This allows you to have a similar cooling capacity as you would have if you had a central air conditioner. However, in this scenario, you won’t need to add any ducts to your home, and you’ll likely save a lot on your energy bills thanks to the unique properties of mini splits that were previously discussed. The ability to control each room’s temperature individually is a great benefit that ensures you never have individuals in your family who are too hot or too cold. This is a standard of comfort that can be difficult to achieve with a conventional air conditioner without significant upgrades.

Keeping Your Home Cool All Summer Long

At Reliable Ducts Heating & Cooling, our main priority is to help keep you and your family comfortable in your Jacksonville home. That’s why we offer repair, replacement, and maintenance services for ductless mini-split air conditioners, central air conditioners and furnaces, and much more. We can also install air purification equipment, upgrade your thermostat, replace or repair your ductwork, and perform many other comfort-related services. We have been serving the area for well over 15 years, providing integrity and customer satisfaction to neighbors throughout the city. Our consistent commitment to quality service is one reason why we consistently receive five-star customer reviews.

9 Benefits of having new ductwork installed


Having your current ductwork cleaned out on a regular basis helps your home out in many ways. Air quality is improved, and your HVAC system might not have to work so hard to operate. However, there are times when maintenance isn’t enough, and you might want to consider the benefits of having new ductwork installed.

Putting new HVAC ductwork in your home can mean many different benefits. The following are nine common ones you might see.

1. Longer HVAC System Lifespan

New ducts are going to be the right size for your HVAC system, and they’re going to be properly sealed. Your HVAC system isn’t going to have to work as hard as it used to in order to deliver the heating and cooling that your home needs. As a consequence, you’ll get more years out of it before you have to replace it, and repairs and maintenance might not happen as frequently along the way. This can be a huge selling point to prospective buyers if your home is going on the market in the next few years.

2. More Space

Older ductwork might actually be quite bulky and take up more room than it needs to. The space you free up might provide storage areas or places for extra insulation. It can even give you a chance to raise ceilings and move walls for a more open-concept living space. You can literally free up valuable space inside your current home.

3. Installation Won’t Take Long

Many home improvement projects can be lengthy affairs that disrupt your family’s daily rhythm. Custom ductwork doesn’t have to be one of those situations. Ductwork is available in many different designs, costs, sizes, and shapes, and you can pick something that gets installed fast. Working with the right professional in advance can create a plan that gets executed quickly and with minimal disruption to your family’s normal activities.

4. Better Energy Efficiency

New ductwork isn’t going to have cracks and holes that bleed hot or cold air. Better energy efficiency is something you’re going to notice on utility bills in the months coming up ahead. An installation might cost you money upfront, but it’s also going to save you money in the future.

5. Enhanced Air Quality

You want clean air in your home. Old ductwork often contains dust and debris that gets circulated throughout your living areas. Ductwork with cracks and holes can also allow pest infestations that can degrade the air you breathe and pose other health risks. New ductwork can help improve what everyone is breathing so that you no longer have allergy episodes, dusty surfaces, and moldy smells. Kids, pets, and older loved ones may stand to benefit the most. If you’ve been using air purifiers in the past, you might not have to do that any longer once you have new ducts installed.

6. Better Temperature Regulation

Once you have new or repaired ducts, you’re probably going to notice the far more consistent temperatures in every room of your home. If there are no more leaks or improperly sized pieces, then cooling and heating should be simple. Your home won’t have “that” warm or cold room anymore. If you’ve been using fans or spot heaters in certain rooms, you may get to put them away for good.

7. Less Noise

Flexible ductwork might start sagging or bending with the passage of time. This will mean air generates more noise as it goes through them. You can eliminate this issue with new ductwork that is both unbent now and less likely to sag in the future. If your kids have trouble sleeping because of creepy noises, that might become a thing of the past.

8. Safety Concerns

When they operate normally, gas appliances ranging from furnaces to laundry machines will release carbon monoxide and other combustion gases via ventilation systems. If your ductwork is leaky, then there might be back-drafting of these gases. New ducts with proper sealing won’t let these gases back into your living space, so you can have greater peace of mind that your family is safe from the dangers of gas leaks.

9. Help the Environment

A lot of energy used in homes and businesses comes from burning fossil fuels in power plants. This leads to acid rain, greenhouse gases, and smog that drive climate change. When you use less energy in your home, your carbon footprint will be less than what it once was, especially if you increase energy efficiency and have new ducts that are properly sealed.

Signs You Need New Ductwork

Knowing the advantages of new ductwork is useful, but how do you know when you need a fresh installation? A professional inspection can be useful, but your ducts might also be showing signs that they’re ready for replacement. Keep an eye out for the following warning signs.

Dust Exiting the Units

It’s common for some dust to come out of ductwork when the HVAC is running. However, if it’s more than you usually see, then you might need to arrange for ductwork installation. Dust can get into the ducts from outside and come into your home, where it makes everything dirty or even harder to breathe inside the home. You can certainly look forward to spending less time cleaning if you get this fixed.

You Can Smell Mildew

 If your nose is picking up something funny from your ducts, then it might be mold. There are times when warm and moist air goes through cold ducts and results in condensation, especially if there isn’t great insulation. This can result in mold growth that might leak with condensation into your ceiling and spread from there.

You Hear Noise

HVAC systems should operate fairly quietly, and that goes for the ducts, too. If there is more noise than there should be, it’s possible that your ducts are either imbalanced or just too small. That puts more strain on your HVAC system than it should and drives your energy and maintenance bills up.

Inconsistent Temperatures

Is one room in your home a lot cooler or warmer than the others? That might be a leaky HVAC duct that’s losing air and its power to keep the home even in terms of temperature. Replacement ductwork might be the only answer to such an imbalance.

Not a DIY Project

 Any of these warning signs might indicate that your current ductwork needs attention or even replacement. You shouldn’t go investigating this yourself, however, as you might create more problems inside your home’s walls. Get a professional to come out and inspect things. They’ve got experience, knowledge, and tools that can diagnose ductwork problems. They can then tell you if a full replacement is warranted or if you can get by with some repairs to the current installation.

Different HVAC Systems and Their Lifespan


An HVAC system is a major purchase for any homeowner. It’s important to know how long your system will last before buying it. We’ll look at the average lifespan of different types of HVAC systems and what you can do to prolong the life of your new system.

Central Air Conditioner

Very few things in life are as essential as a central air conditioner. Most units have a lifespan of about 15 years. Several factors can affect how long your unit will last, such as the quality of the unit, installation, maintenance, and how often it is used. You can help extend the lifespan of your air conditioner by having it serviced regularly and using it wisely.

At [company_name], we typically recommend that our customers have their systems serviced every two years. This helps to ensure that your system is running efficiently and effectively, and it also helps to prolong its lifespan.

Quality Air Conditioning with Lower Utility Bills


A window unit and an HVAC system will provide a change in room temperature with different costs and air quality. A window unit is cheaper than an HVAC system. If you live in a home that has newer windows with energy-efficient glass, keeping your home cool will be easier with a window unit and less expensive to operate. An HVAC system and a window unit can provide the same cooling quality, but the costs will differ, and the air quality inside your home may vary.
A window unit provides air for only one room at a time since there are no ducts for better circulation in your home. With higher utility bills from running the AC constantly, these units typically cost more monthly than an HVAC system. However, for a long-term investment strategy to save costs on your utility bills, an HVAC system is most suitable. It is more energy-efficient than a window air conditioning unit. As energy prices continue to increase, you may want to consider a window unit for temporary relief with lower utility bills. If you have allergies or asthma, the fine particles of dust from a window unit can make you ill or worsen your allergies or asthma.
An HVAC system can help improve indoor air quality with extra insulation and fewer dust particles circulating throughout your home. An HVAC system assures higher air quality than the conventional window unit. If you live in a house that lacks ducts, it may cost more to install one than a window unit.
Therefore to answer your question on whether window units are cheaper than HVAC systems, yes, they are, but you need to compromise the quality of the cooling system you get. Window units can be expensive in the long run and uncomfortable, especially if your home has more than five rooms. Installing individual window units will dig an enormous hole in your pocket. Window units may be cheaper to operate, but you will get less bang for your buck. You are better off with an HVAC system and ducts.

What Can Your Home Electrical System Handle?

To decide what air conditioning your home needs, we recommend considering your electrical input and output. Your home should be able to run and manage your desired HVAC system without unnecessary breakdowns or inefficiency. Your electrical input is rated in amps, measuring how much electricity your household will draw. A properly sized air conditioning unit for your home should not strain the electrical input of your home. We can do the math for you and assure you that your air conditioning system is safe to run in your home.
Picking an incompatible pair will result in additional bills for repairs and unnecessary maintenance. Your home needs a stable electrical inlet and outlet to prevent power surges that may fry your air conditioning system. The determinants to consider are the age and condition of your power source. If your home is solar-powered, you have the upper hand in installing the best air conditioning systems without fear of energy waste. Your HVAC system must power itself with minimal electricity or use electricity as infrequently as possible.

Ductless Air Conditioning Systems Are Worth It

Ductless air conditioning systems are best for large homes due to the larger surface area to control the room temperatures. The ductless air conditioning systems are very efficient in terms of power consumption, but their price tag is a little higher than the conventional air conditioners. Also known as the mini-split unit, the system incorporates a technological thermostat system that allows individual room adjustments. The thermostats are located internally while the cooling fans are installed externally, providing a quieter environment while switched on.
The ductless air conditioning system has a digital timer display to record and present the energy consumption rate. Additionally, the system has a programmable heat setting allowing for suitable heating and cooling effects on individual rooms. Installation of the ductless air conditioning system is simple and easy. A conventional air conditioner may consume more energy in cooling a small space than a ductless air conditioner consumes in a larger room.
The main benefits of the ductless air conditioning system are its low maintenance costs, silent operation, and cost-efficiency. We offer professional installation for an energy-efficient ductless air conditioning system to help lower your utility bills in the long run.

Window Units Are Cheap but Not Effective

Window units are suitable for the temporary cooling of single rooms. They are based solely on remote heat exchange, and thus they cannot be used as a heat pump. Only the advanced window units can use the warmth inside your house to reverse a cooling effect. They rely on the low temperature of the air coming in and out of your home.
The built-in fan blows at low speed, which causes low noise but keeps the room cool for short periods. Installing a window unit will be a great inconvenience to your home during the summer due to the extremely high temperatures outside and slow cooling indoors. Therefore, we recommend you only install a window unit under the following circumstances:

  • Your home is a rental apartment
  • Hot climates outside are temporary
  • Your home lacks existing ductwork
  • Your home has an outdated cooling system

The advantages of this system include:

  • Quick installation
  • Affordable prices
  • Less energy consumption
  • Short term investment

The cons of installing this system include:

  • No air filtration property
  • Uneven temperature regulations
  • Temporary cooling effects
  • Limited to one room

HVAC Systems Are Expensive but Efficient

HVAC systems are a permanent solution to your air conditioning problem. They are durable and come with a long life span with minimal maintenance. Their major drawback is the expensive installation costs. Your home size determines the installation costs due to work needed. HVAC systems consist of air ducts and air ductwork, thermostats, blower motors, cooling fans, warm-air registers, and vents to distribute the cool air throughout your home.
The system is controlled by a thermostat that monitors and adjusts the temperature in your home. An HVAC system with an Energy Efficiency Ratio upgrade is considered efficient and cost-effective. We recommend installing an HVAC system for a long-term solution to heating and cooling your rooms separately. The additional software that predicts your home needs regulates energy consumption by shutting off when even suitable temperatures have been achieved. It is an energy-efficient masterpiece in your home.

How to Determine the Energy Efficiency of the HVAC System of Your New Home


Your HVAC system accounts for approximately 40% of your home’s cooling needs. Efficient heating or cooling equipment can reduce the energy consumption in your home. When moving to a new house, it’s wise to assess the efficiency of the existing unit. Here are tips on how to determine the performance of your HVAC system.

Inspect the Equipment for Deterioration

When moving to a new home, you ought to assess your heating and cooling system. You can start by inspecting the HVAC unit for signs of deterioration around the equipment. Pools of water and corrosion on the casing imply the system is aging and inefficient.

Corrosion can damage the condenser coils by gradually creating a patchwork of cracks on the tubes. Statistics suggest rusting is responsible for up to 40% of equipment failures.

When the copper coils succumb to corrosion, the system will leak the refrigerant and reduce the efficiency of your system. Every HVAC system has a specific refrigerant charge corresponding to its heating and cooling load. Inadequate amounts of the fluid could force your furnace to overheat or the coils to freeze over in winter.

You can arrange for HVAC system maintenance so that technicians can clean the coils and restore their efficiency. Grime can also create an insulation layer that impacts heating and cooling. If the copper tubes are defective, a professional will recommend a replacement.

Determine the Energy Efficiency of the HVAC System

After examining the equipment’s condition, locate the energy rating label. HVAC systems have a yellow and black sticker with SEER and AFUE ratings. An Energy Star label indicates the system’s performance is higher than standard equipment of the same size.

The SEER rating (Seasonal Energy Efficiency Ratio) indicates the air conditioner’s efficiency. SEER calculates the cooling output against the fuel consumption for the entire season. SEER ratings start from 13 and can go up to 25.

SEER values will be on the manufacturer’s energy guide with the rating, which often includes additional characters. For example, the rating could be written as AC15. It means the air conditioner has a 16 SEER rating.

AFUE (Annual Fuel Utilization Efficiency) is a rating that measures the heating component’s efficiency. Older boilers and furnaces have an AFUE rating of 78 and 80%. The latest heating and cooling equipment can have an AFUE of up to 98%.

Keep in mind the efficiency of the HVAC system can deteriorate due to aging or insufficient maintenance. Even a new system can deteriorate in performance and raise the operational costs for the system. Reliable Ducts Heating and Cooling technicians can inspect your equipment in Jacksonville to determine its performance.

Examine the Ductwork

When assessing the performance of the new home’s heating and cooling system, be sure to examine the ductwork. The ductwork distributes conditioned air to different rooms through the supply vent and expels it through the return vent.

According to Energy Star, improper installation of air ducts is among the leading reasons new systems become inefficient. Leaks and holes on the ductwork allow conditioned air to escape, increasing your equipment’s energy consumption.

Besides improper installation, the ductwork can develop holes and gaps between connections. Lack of ductwork insulation may lead to energy losses that force your HVAC system to work harder. Your equipment can overheat and damage components.

A visual examination can spot inefficient ductwork. Tangled and loose connections indicate the tubes need sealing or a replacement. Strange noises such as hissing and banging could be a symptom of a leak.

Also, check if the vents are open to avoid damaging your HVAC system. It is a misconception that closing the vents can reduce energy consumption. But the ductwork is designed to match the building’s heating and cooling needs. Closing off the vents will only force your AC and furnace to overwork.

Some issues are not easy to identify through a visual inspection. That’s why HVAC technicians recommend consulting a professional for an assessment. Professionals can evaluate the sizing and insulation and can advise you on the best options for your Jacksonville home.

Pay Attention to Indoor Air Quality Issues

Your new home’s indoor air quality is another factor that may indicate the heating and cooling system’s performance. Be sure to check surfaces for dust accumulation. Dust is a sign of poor circulation, probably caused by clogged filters or leaky ductwork.

Dust can start a vicious cycle that rapidly deteriorates your unit. Dusty condenser and evaporator coils can force your HVAC system to overwork. Your HVAC equipment will eventually break down and may require a replacement.

Unusual odors could be an indication of mold and mildew growth. Improper ductwork insulation or air leaks can introduce moisture into the system. The humidity could trigger corrosion or cause premature failure of your HVAC equipment.

Inconsistent Temperatures Across the House

An inefficient HVAC system will overwork to circulate conditioned air throughout the house. You may detect temperature differences across different rooms. The imbalance in temperature could be due to ductwork leaks or substandard equipment installation.

Your equipment may fail to heat or cool the house if its capacity is too big or too small. If its size exceeds the needs of your home, the AC will shut on and off to avoid overheating. The continuous on and off operation can speed up the deterioration of critical components.

If your equipment is too small, it will keep running continuously to meet your home’s energy demands. The system can overheat components, causing premature failure. The longer heating and cooling cycles will cause temperature imbalances across the house.

Therefore, it is best to schedule an inspection when you suspect temperature imbalances across the room. Our technicians can assess the ductwork and the quality of the installation. Talk to Reliable Ducts Heating and Cooling for top-notch heating repair solutions in Jacksonville.

How to Determine if You Need a Replacement

An aging HVAC system approaching the end of its life can be expensive to run. Not only will it raise your energy bills, but you’ll also have to schedule repairs frequently. The equipment will deteriorate faster, requiring costly parts replacement in the long run.

The lifespan of an HVAC system is between 10 and 15 years. Consider replacing a system that is more than a decade old, especially if it is inefficient. Acquiring a new system may make sense in the long term compared to spending money on multiple repairs.

However, you don’t have to replace a system more than a decade old. It depends on the quality of installation and the frequency of maintenance. You can request a history of the HVAC maintenance records to evaluate its performance.

A professional inspection is the best way to determine if you need a replacement. A certified technician can offer insights on improving the system’s efficiency. You can also get more information on new technologies and features and the ideal HVAC equipment for your needs.

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.
