Your heat pump works almost every day of the year here
Greenville County needs heat or cooling twelve months a year. Winter nights average 34°F from December through February, mild enough that a heat pump can carry the heat load itself without leaning on backup heat strip too often. Summer afternoons average 87°F, and that heat pump runs the other side of the year too, from May through September.
A new split-system heat pump has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, the federal minimum for units built since 2023. With power out at least 24 hours for 45% of South Carolina households last year, and 122 damaging wind events across the state over the past ten years, a heat pump that comes back on by itself once power returns matters here.

- Is a heat pump better than a furnace?
- It depends on what you're comparing it to and what you're heating with now. A heat pump moves heat instead of burning fuel to create it, so it can heat and cool from one system, and it costs less to run than electric resistance heat. Here, where 56.9% of homes heat with electricity, that difference matters. If you're on gas already, the choice is less clear cut, and a contractor can walk through what makes sense for your house.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only cools. A heat pump does the same job in summer, moving heat out of your house, but it can also run in reverse and move heat into your house in winter. Since homes here need heat seven months of the year and cooling five, a heat pump covers both jobs a furnace and an AC would otherwise split between them.
- Does a heat pump work in cold weather?
- Yes. A heat pump pulls heat from outside air even when it's cold, though it has to work harder as the temperature drops. Winter nights here average 34°F, which is well within the range a heat pump handles without trouble. In much colder climates, some homes pair a heat pump with a backup heat source, but that's not a typical concern at these temperatures.
