Know What Heating System You Have

Troubleshooting depends entirely on the type of heater in your home. Gas furnaces, heat pumps, electric furnaces, and boilers each have distinct failure modes. Not sure which one you own? Check outside — if an outdoor unit operates during winter, you have a heat pump. An indoor-only unit with a gas line is a gas furnace. No outdoor unit and no gas connection usually means an electric furnace. Identifying your system upfront saves valuable time whether you're troubleshooting on your own or describing the problem to a technician.

Checks That Apply to Every Heater Type

No matter what kind of heater you have, run through these steps first: verify the thermostat is on "heat" with the target temperature set above the current room temp. Inspect the air filter — a plugged filter triggers shutdowns across all heater types. Confirm the circuit breaker is in the on position. Locate the furnace power switch (if one exists) and make sure it hasn't been toggled off. For heat pump owners, examine the outdoor unit for snow buildup, ice, or debris — anything restricting airflow around the outdoor coil will hamper heating performance.

Heat Pump Quirks in WNC's Cold Weather

Heat pumps are a popular choice across Western North Carolina, but their cold-weather behavior differs from traditional furnaces. Once temperatures dip below around 35°F, efficiency declines and auxiliary heat strips are supposed to engage as backup. If your heat pump delivers only lukewarm air on frigid days, the aux heat may not be activating — frequently a relay or sequencer malfunction. Also note that periodic defrost cycles are completely normal during winter; the outdoor unit may produce what looks like smoke or steam for a few minutes before resuming normal operation.
