Ten months of work a year, either heating or cooling
Anderson County only gets a couple of months of rest. Heat runs November through March, with winter nights averaging 34°F. Cooling runs May through September, with afternoons averaging 89°F. That is ten months where the system is doing one job or the other.
Most homes here heat with electricity, so the furnace or heat pump and the electric grid are both working through those cold nights. And the grid here is not always steady. Nearly half of South Carolina households lost power for at least a day in 2024, and the county has logged 111 damaging wind events over the past ten years. A new system should be sized right for both the summer heat and the winter cold it will actually see here, not just installed and hoped for.

- When should I replace my HVAC system?
- Replace it when repairs get frequent or a contractor tells you the heat exchanger or compressor is failing. The age on the nameplate matters less than what's actually going wrong with it. If it's short-cycling, making noise it didn't used to make, or a technician keeps finding a new problem every visit, those are the signs it's done. Homes here run the heat or the AC ten months out of the year, so a system on its way out doesn't get much rest to hide the problem.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, yes. A furnace and air conditioner installed together are matched to work as one system, and pairing a new one with an old one can mean the new unit never runs at its rated efficiency. It also means you avoid paying for labor twice within a few years of each other. If one unit is much newer than the other, a contractor can tell you whether it's worth keeping for now.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, then sets the new ones in place and connects them to the ductwork, gas line or electrical circuit, and the refrigerant lines. They check the ducts for leaks and make sure the new equipment is sized right for the house, since a unit that's too big or too small won't heat and cool evenly. Once it's running, they test it and set the thermostat. A contractor can walk you through the specifics for your house, including how long the job will take.
