Ten months of work a year, in weather that doesn't let up
Your furnace runs November through March here. Your air conditioner runs May through September. That's ten months where one or the other is working, with only short stretches in spring and fall when neither has to.
Winter nights average 37°F, so the burner is cycling on and off most nights of the season. Summer afternoons average 91°F, and the compressor runs long stretches to keep up. Most homes here heat with electricity, so when the power goes out, the heat goes with it. That happens more than you'd think. Orangeburg County has seen 177 damaging wind events over the past ten years, and in 2024 close to half of South Carolina households lost power for a full day or more. Every time the power comes back, your system has to start up cold and catch up on top of a season that already asks a lot of it.

- Why is my heat not working?
- Most often it is the thermostat, the power to the unit, or the igniter. If your thermostat screen is blank, check the breaker first. Gas furnaces will not light without a working igniter or flame sensor, and if either has failed, the furnace will try to start and then shut back down. Most homes here heat with electricity, so a tripped breaker or a heat pump stuck in defrost mode is worth checking before anything else. If the breaker is fine and the thermostat has power, a contractor will need to look at the igniter, the flame sensor, or the heat pump's outdoor unit.
- Why is my system running but not cooling the house?
- The fan is moving air, but something between the air handler and your rooms is not doing its job. A dirty filter is the first thing to check, since a clogged filter chokes airflow and can even freeze the coil. If the filter is clean, low refrigerant or a failing compressor can keep the air moving without it actually being cold. On a 91 degree afternoon, a system fighting a dirty filter or low refrigerant will run long and still lose the battle, so this is not something to leave for a mild day to sort out.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it is set to heat or cool as needed, the batteries are good, and the temperature setting actually calls for the system to run. Next check the breaker box for a tripped switch, since a reset there solves more no-heat and no-cool calls than anything else. Look at the filter and replace it if it is gray or clogged. Outside, clear leaves or debris away from the outdoor unit. With 177 damaging wind events recorded here over the past ten years, it is also worth a quick look at the outdoor unit for storm damage, bent fins, or debris blown into the housing before assuming the problem is internal.
