Aux heat above 40°F for more than an hour or two is a fault; below it, the system is doing its job. The six causes in order of cost, and the settings that stop it.
A healthy cooling cycle runs 15 to 20 minutes. Repeated five-minute cycles wear out the compressor. How to tell an airflow problem from an oversized system.
The click means the thermostat is fine, so the fault is downstream. What you hear at the equipment tells you whether it is power, the contactor or the capacitor.
A blank thermostat is almost never a dead thermostat — it is an interrupted 24V supply. The furnace door switch, the breaker, the float switch, the 3A fuse and the C wire, in the order worth checking.
Light frost that clears within 15 minutes is the system working; solid ice that never clears is not. How to tell which you are looking at, and what is safe to do about it.
Manufacturers say nearly every inaccurate thermostat is a placement problem, not a calibration one. The test that tells you which you have, and when an offset actually helps.
A heat pump moves about 67% more air at a lower temperature, so hours-long cycles are the mechanism rather than a fault. Here is when constant running really is a problem.
Heat pump air runs 90-110°F against a furnace's 125°F, so it feels cool on your hand while still heating the house. Here is how to tell normal defrost behaviour from a real fault.
EM heat switches your heat pump off entirely; aux heat runs alongside it. Confusing the two can leave your most expensive heat source running all winter without anything feeling wrong.
Smart thermostats are causing $200-500/month spikes in heating bills by running expensive AUX heat too aggressively. Here's how to fix it in under 10 minutes.
