A heat pump here works almost every month of the year
In Spartanburg County a heat pump runs from October through April to keep the house warm. Then it switches over and runs May through September to keep it cool. That is 12 months a year with barely a break between seasons. Winter nights average 33°F. Summer afternoons average 88°F. The same system has to handle both, reliably, in both directions.
Any split-system heat pump installed now has to meet federal minimums of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. That is the baseline a new install starts from. Worth planning for too. The area has seen 125 damaging wind events over the past ten years, and 45% of South Carolina households went at least 24 hours without power in 2024. Most homes here heat with electricity, so when the power goes out, the heat pump goes with it until the power comes back.

- 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, all from one system. A furnace only burns fuel to make heat, so you'd still need a separate air conditioner for summer. Here, homes need cooling from May through September and heat from October through April, so having both jobs covered by one system matters. Whether a heat pump suits your house better than a furnace and separate AC depends on your ductwork and your current setup, which a contractor can look at.
- 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 can do that too, but it can also run in reverse and move heat into your home when it's cold outside. Inside your house, they look and sound about the same. Both use a compressor and a coil. The difference is that a heat pump has a reversing valve, so it works as your cooling system in summer and your heating system in winter.
- Does a heat pump work in cold weather?
- Yes. A heat pump pulls heat from outside air even when that air feels cold, because there's still heat in air well below freezing. Winter nights here average 33°F, which is well within the range a heat pump handles without trouble. Heat pumps sold new today also have to meet a federal minimum of 7.5 HSPF2, a rating that reflects how they perform across a full heating season, not just on mild days.
