Gaffney runs its system almost year round
Heat runs October through April here, then cooling takes over for May through September. That leaves your system idle only a few weeks a year, and most of that work falls on the same electric setup, since almost seven in ten homes here heat with electricity.
Winter nights average 32°F, cold enough that the system cycles on and off for hours at a stretch, and summer afternoons average 88°F, which keeps the compressor under load most of the day. Cherokee County has seen 49 damaging wind events and 6 winter storms over the past ten years, and statewide, almost half of households lost power for at least a day in 2024. When the power drops and comes back, most systems restart on their own, but a system already worn from months of steady use is the one that fails to.

- Why is my heat not working?
- Start with the thermostat and the breaker before you assume the worst. Check that the thermostat is set to heat and a few degrees above room temperature, and check the breaker panel for a tripped switch. If you have a gas furnace, look for a pilot light or igniter that isn't lighting, since that's a common reason heat stops on a cold night. If power and settings check out and you still have no heat, the problem is likely inside the furnace or heat pump itself, and that calls for a contractor to look at it. With winter nights here averaging 32°F, it's worth getting this checked quickly rather than waiting.
- Why is my system running but not cooling the house?
- If the system runs but the air isn't cold, the first thing to check is the filter. A clogged filter chokes off airflow across the coil, and when that happens the coil can freeze up and stop cooling altogether. Check outside too, since the outdoor unit needs open space around it to release heat, and anything blocking it will cut into cooling. If the filter is clean and the outdoor unit is clear but you still get warm air, the system may be low on refrigerant or have a failing part, and that's a job for a contractor to diagnose. On an 88°F afternoon here, a system that's losing the fight against the heat needs attention before it stops keeping up entirely.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it's set correctly, has working batteries if it uses them, and is actually calling for heat or cooling. Next check the breaker panel for a tripped breaker, since a reset there solves more problems than people expect. Check the filter and pull it out if it looks gray or clogged, since a blocked filter causes both heating and cooling problems. If you have a gas furnace, look for a pilot light or igniter light that should be on. If all of that looks normal and the system still isn't working right, a contractor will need to look at what's inside the unit.
