Ten months of work a year, with storms in between
Your system in Anderson County works most of the year. Heat runs November through March, and cooling runs May through September, with summer afternoons averaging 89°F. That kind of stretch wears on the compressor and the fan motor, since they run long hours with little rest.
Winter nights average 34°F here, cold enough that the heat runs steadily but not so cold that most furnaces or heat pumps struggle to keep up. Most homes here heat with electricity, so when the power goes out, the heat goes with it. That matters in this area. Over the past ten years the county has seen 111 damaging wind events, and in 2024 almost half of South Carolina households lost power for at least a day. Most systems restart on their own once power returns, but if yours does not, that is worth a call.

- Why is my heat not working?
- Start with the thermostat and the power to the furnace. If the thermostat screen is blank, check the breaker and any switch that looks like a light switch near the furnace itself. Most furnaces with a standing pilot will relight on their own once power is back, but an electronic igniter can fail and needs a contractor to replace it. With winter nights here averaging 34°F, a furnace that will not fire is worth calling in the same day rather than waiting.
- 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 the coil can ice over so the air coming out feels weak or barely cool. Turn the system off for a few hours to let any ice melt, then replace the filter and see if cool air returns. If the outdoor unit is running but the air inside is still warm, the system is likely low on refrigerant or has a failing part, and that needs a contractor to diagnose. With afternoons here reaching 89°F, this isn't something to let ride for days.
- What can I check before calling for HVAC repair?
- Check the thermostat batteries and settings first, since a dead battery or a setting bumped to the wrong mode looks like a bigger problem than it is. Check the breaker box for a tripped breaker. Check the air filter and replace it if it's gray or clogged, since restricted airflow causes problems in both a furnace and an air conditioner. If the system still isn't working after that, a contractor will need to look at it directly.
