Quick Answer
AUX on the thermostat in December means the strips are on. When that is normal in Wesley Chapel, and when it is a repair.
Start here before you book service
- ✓ AUX for a few minutes on a cold start can be normal.
- ✓ AUX all evening on a mild December afternoon is not.
- ✓ Emergency heat is the strips only. Put the mode back to Heat after a test.
- ✓ Below about 35°F the strips are backup, not the all-day setting.

AUX means the strips are helping
Auxiliary heat on a Wesley Chapel thermostat is the electric strips inside the air handler. The heat pump is still the main heat. The strips come on when the room is far below the setpoint, or when the outdoor air is cold enough that the heat pump cannot close the gap alone. The screen says AUX, auxiliary, or sometimes emergency, and those words are not the same thing.
December at the Tampa station is the first month heating degree days pass cooling degree days: a high of 73.9°F, a low of 55.9°F, 105 heating degree days, and 102 cooling degree days (Florida Climate Center, 1991-2020). People in the United States search “auxiliary heat” about 6,600 times a month. In December 2025 that count was about 18,100 (Google Ads, United States). It is not a Wesley Chapel volume. “Heat pump repair Wesley Chapel” stays at the ads floor of 10.
When AUX is the normal start
On a cold morning the thermostat can call the strips for a few minutes while the heat pump catches up. The outdoor fan should still run if the mode is Heat. The supply air gets warm. AUX then drops off. That sequence is a heat pump doing its job in Meadow Pointe or Seven Oaks.
Below about 35°F the strips are the backup. A Wesley Chapel afternoon in December is often in the 70s, so an all-day AUX light on a mild day is not that backup. It means the heat pump never took the call, the lockout is set too high, or the thermostat was left on emergency heat. Emergency heat skips the outdoor unit. The strips carry the house, and the electric bill shows it.
What to write down
Set the mode to Heat. Set the fan to Auto. Note whether the outdoor fan runs while the screen says AUX. If the outdoor unit stays off and the strips run through a 70-degree afternoon, stop there. The repair is the control or the thermostat, not another bag of refrigerant. The page for a system that never warms is heat pump not heating. The shop page is heating service. Call (813) 395-2324. Hours are Monday through Friday 8 a.m. to 6 p.m. and Saturday 10 a.m. to 4 p.m.
