Eleven months of work a year in Sevier County
Your furnace runs October through April here, and your AC picks up June through September. That leaves only one month where neither system is working. Winter nights averaging 30°F mean the burner cycles on and off for hours at a stretch, and each start puts wear on the igniter and the ignition control. Summer afternoons near 84°F keep the compressor running long stretches too, and that heat is hard on the run capacitor.
Most homes here heat with electricity, so a winter storm that knocks out power stops your heat outright, not just the fan and thermostat. Sevier County has seen 68 winter storms and 157 damaging wind events over the past ten years, and across Tennessee, 20 percent of households went at least 24 hours without power in 2024. Most systems restart on their own once power comes back, but if a part was already failing before the outage, that is often when it finally gives out.

- Why is my heat not working?
- Start with the thermostat and the breaker before you assume the worst. If it's set to heat and a few degrees above room temperature but nothing kicks on, check the breaker panel for a tripped switch. Power blips are worth ruling out here, since a fifth of Tennessee households lost power for a full day or more last year. If the breaker is fine and the thermostat is set right, the igniter or the flame sensor is a common next suspect, and that's a job for a contractor to check safely.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and when that happens the coil can ice over, so the blower runs but the air coming out feels weak or warm. Also look at the outdoor unit and clear away any leaves, grass clippings or debris sitting against it, since it needs open airflow to release heat. If the filter is clean and the outside unit is clear but the house still isn't cooling, the system may be low on refrigerant, and that requires a contractor to find and fix the leak.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the breaker panel, and the air filter, in that order. Make sure the thermostat is set to heat or cool as needed and the temperature is set past room temperature. Look at the breaker box for anything tripped, since this area sees plenty of wind and winter storms that can knock power out. Then pull the filter and hold it up to a light. If you can't see light through it, replace it, since restricted airflow is behind a lot of the calls that turn out not to need a repair at all.
