Ten months of work a year in Anderson County
Your heat pump runs from November through March to keep the house warm, then May through September to keep it cool. That's ten months a year with barely a break between seasons. Winter nights average 34°F here, mild enough that a heat pump can carry the heating load on its own most of the time. Summer afternoons average 89°F, which asks a lot of the outdoor unit through a long cooling season.
Any split-system heat pump installed new has to meet federal minimums of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. Power matters too. Most homes here heat with electricity, and 45% of South Carolina households lost power for at least 24 hours at some point in 2024. Between damaging wind and the occasional winter storm, a heat pump that comes back on by itself when the power does is worth asking about.

- Is a heat pump better than a furnace?
- A heat pump does something a furnace can't. It cools your home in summer and heats it in winter, so you're running one system instead of two. Anderson winters average 34°F at night, mild enough that a heat pump can carry the heating load without much trouble. A furnace only heats, so if you already have central air, a heat pump replaces two pieces of equipment with one.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only moves heat out of your home. A heat pump does the same thing in summer, but it can also run in reverse and pull heat from the outside air into your home in winter. That's the whole difference, the heat pump has a valve that lets it switch directions. An air conditioner can't heat your home at all.
- Does a heat pump work in cold weather?
- Yes, a heat pump pulls heat from outside air even when it's cold, down to well below freezing. Anderson winter nights average 34°F, which is comfortably within the range a heat pump handles well. As the outside temperature drops, a heat pump has less heat to work with and has to run longer to keep up, but it doesn't stop working at 34 degrees.
