Identify Your Heater Type First

The troubleshooting steps depend on what type of heating system you have. Gas furnaces, heat pumps, electric furnaces, and boilers each fail differently. If you're not sure what you have, look at your outdoor unit — if it runs in winter, you have a heat pump. If you only have an indoor unit with a gas line, that's a gas furnace. If there's no outdoor unit and no gas line, you likely have an electric furnace. Knowing this saves time when troubleshooting or explaining the problem to a technician.

Universal Checks for Any Heater

Regardless of heater type, start with these: confirm the thermostat is set to "heat" and the set point is above room temperature. Check the air filter — a clogged filter causes shutdowns in all heater types. Verify the circuit breaker is on. Make sure the furnace power switch (if present) is in the "on" position. For heat pumps, check that the outdoor unit isn't buried in snow, ice, or debris — restricted airflow around the outdoor coil prevents proper heating.

Heat Pump–Specific Issues in WNC

Heat pumps are extremely popular in Western North Carolina, but they behave differently in cold weather. Below about 35°F, a heat pump's efficiency drops and auxiliary heat strips should kick in to supplement. If your heat pump blows lukewarm air on cold days, the aux heat may not be engaging — often a relay or sequencer issue. It's also normal for a heat pump to go into defrost mode periodically in winter, during which the outdoor unit appears to smoke or steam. This is normal and lasts only a few minutes.
