Florida Cold Fronts Are Here: What to Know About Your Heat Pump This Time of Year
December in Florida doesn’t usually mean winter coats—but it does mean sudden cold fronts. One day your AC is running, the next your heater kicks on for the first time in months. When that happens, many homeowners are caught off guard by strange smells, high energy bills, or heating systems that don’t seem to work properly.
If your home relies on a heat pump, understanding how it works during cold weather can help you avoid discomfort and unexpected repair calls.
Why Florida Homes Use Heat Pumps
Most homes in Brandon, Tampa, and Riverview rely on heat pumps, not traditional furnaces. Heat pumps are efficient and ideal for Florida’s mild winters—but they behave differently during cold snaps.
Instead of creating heat, a heat pump moves heat from outside air into your home. When temperatures drop, that process becomes less efficient, and your system relies on backup heating.
What Is “Aux Heat” and Why It Matters in December
When outdoor temperatures dip into the 40s or lower, your system may activate auxiliary (emergency) heat—often electric heat strips.
This is completely normal, but it can lead to:
Higher energy bills
Dry or hot air blowing suddenly
Longer run times
Systems struggling if not properly maintained
If aux heat runs too often, it may indicate your system needs service.
Common December HVAC Issues We See in Florida
During cold fronts, homeowners often call for:
Heat blowing lukewarm or cold
Burning smells when heat is first turned on
System running constantly
Sudden spikes in electric bills
Thermostat confusion between heat and cool modes
Most of these issues are preventable with a professional inspection.
5 Ways to Prepare Your HVAC System for Cold Fronts
1. Test Your Heat Early
Don’t wait for the coldest night of the year. Turn on your heat now and make sure it responds correctly.
2. Replace Dirty Filters
Restricted airflow forces your system to work harder—especially when aux heat activates.
3. Check Thermostat Settings
Incorrect settings can cause unnecessary aux heat usage, driving up energy costs.
4. Schedule a Heat Pump Inspection
A technician can test heat strips, defrost cycles, electrical components, and overall efficiency.
5. Seal Air Leaks
Drafty doors and ducts make your system run longer and reduce comfort during cold nights.
Don’t Let the Next Cold Front Catch You Off Guard
Florida winters may be short, but HVAC problems during cold snaps are extremely common—especially for systems that haven’t been checked since last year.
