Florida Winters Are Mild — But Not Maintenance-Free
While Jacksonville doesn’t see snow, local homeowners still rely on their HVAC systems for warmth on chilly nights. Florida’s humidity, salt air, and fluctuating temperatures can quietly strain your system — especially when you switch from cooling to heating for the first time in months.
Preparing your HVAC system for winter ensures comfort, efficiency, and peace of mind through the cooler season. Here’s what Jacksonville homeowners should do before temperatures drop, courtesy of Reliable Ducts Heating & Cooling — your trusted local HVAC experts.
1. Switch to Heating Mode Early and Test Your System
Don’t wait for the first cold snap to find out your heat isn’t working. Early December is the perfect time to test your system. Turn your thermostat to “heat” and let it run for 10–15 minutes.
Listen for unusual noises, check for airflow at the vents, and make sure warm air is circulating properly. If you notice a burning smell or no heat at all, it could indicate dust on heating elements, blocked vents, or a malfunctioning igniter.
Reliable Ducts offers fast, same-day heating repairs in Jacksonville, so you don’t have to wait when the cold hits.
2. Replace or Clean Your Air Filters
Dirty filters are one of the top causes of poor airflow, uneven temperatures, and system strain. As winter begins, change your filter to help your system breathe easier and prevent excess wear on motors and fans.
For homes with pets or family members with allergies, consider upgrading to a HEPA-rated or electrostatic filter to capture fine particles and improve air quality all winter long.
3. Inspect and Clean Air Vents and Ducts
Closed windows and longer indoor hours make clean air more important than ever. If dust puffs out of vents when your system starts up, it’s time to have your ducts inspected.
Reliable Ducts Heating & Cooling provides duct cleaning and sanitization services throughout Jacksonville to remove allergens, dust, and mold buildup that can compromise air quality and efficiency.
Clean ducts also help your heater distribute warm air evenly — saving energy and keeping every room comfortable.
4. Check Your Thermostat Settings and Battery
Your thermostat is the brain of your HVAC system. Incorrect settings can waste energy and make your home uncomfortable.
Set your thermostat to 68–70°F when home and slightly lower when you’re away to conserve energy. If you’re still using an older model, upgrading to a smart thermostat lets you adjust temperatures remotely and track energy usage in real time.
Before winter starts, replace the thermostat battery to avoid sudden shutdowns.
5. Schedule a Professional Heating Tune-Up
Even a mild winter puts demands on your system. A professional tune-up in early December ensures your heater is operating safely and efficiently.
During a service visit, Reliable Ducts technicians will:
- Inspect electrical components and safety switches
- Lubricate motors and moving parts
- Check the blower, belts, and filters
- Test airflow, carbon monoxide levels, and temperature output
- Identify early signs of wear or malfunction
This proactive approach prevents unexpected breakdowns and ensures your system performs when you need it most.
6. Seal Leaks Around Windows and Doors
A drafty home can make your HVAC system work overtime. Check for gaps around doors, windows, and attic access points. A few dollars’ worth of weather stripping or caulk can save you hundreds on your energy bills each year.
Sealing leaks also helps maintain consistent indoor temperatures, allowing your HVAC system to cycle less frequently and last longer.
7. Plan Ahead for Cold Snaps
Jacksonville may only get a few nights in the 30s, but when it happens, demand for heating repairs skyrockets. That’s why early preparation is key.
