Twelve months of work, in a county that loses power

Your system runs almost the whole year here. Heat from October through April, seven months, then cooling from May through September, five more. There is no real off season, so a weak part does not get much time to hide.

Winter nights average 32°F, cold enough that the burner or the heat pump cycles on and off for hours at a stretch. Summer afternoons average 87°F, and the compressor answers by running long stretches to keep up. Loudon County has seen 10 winter storms and 60 damaging wind events over the past ten years, and across Tennessee one household in five went at least 24 hours without power in 2024. Most homes here heat with electricity, so when the power drops, the heat drops with it. When it comes back on, the system has to start cold and catch up, which is when a weak igniter, a tired capacitor, or a struggling motor finally gives out.

Why is my heat not working?
Start with the thermostat. Make sure it is set to heat and the temperature is set above the room temperature, since a setting bumped by accident is more common than it should be. If the thermostat looks right, check your breaker panel for a tripped switch, especially after a storm. Most furnaces will not run at all if the flame sensor is dirty or the igniter has failed, and that calls for a contractor to look at it. If you heat with electricity, which most homes here do, a tripped breaker on the heat strips can leave you with cold air blowing from the vents instead of no air at all.
Why is my system running but not cooling the house?
Check your air filter first. A filter clogged with dust blocks airflow across the coil, and the coil can ice over when that happens, which makes the problem worse the longer the system runs. Next check the outdoor unit and clear away any leaves, grass clippings or debris around it, since the coil out there needs open air to release heat. If the filter is clean and the outdoor unit is clear but the air coming from the vents is not cold, the system likely needs a contractor to check the refrigerant charge and the coil itself.
What can I check before calling for HVAC repair?
Check the thermostat settings, the batteries in it if it uses any, and the breaker panel for a tripped switch. Check the air filter and replace it if it is gray with dust, since a dirty filter causes both heating and cooling problems. Look at the outdoor unit and clear leaves or debris away from it. If the system still is not working after that, a contractor will need to diagnose it, and telling them what you already checked saves time on the visit.
