Do heat pumps work when it freezes in Greenville?

Yes. Modern heat pumps are rated for cold-climate performance and can provide heat well below freezing. Auxiliary heat strips provide backup for extreme cold.

Is a heat pump more expensive than a furnace?

A heat pump can cost more upfront than a basic furnace, but it replaces both the furnace and the air conditioner, so the total system cost is often comparable or lower.

Heat Pump vs. Furnace in South Carolina

Section 1

How each system heats your home

A heat pump moves heat from outside air into your home. It reverses in summer to act as an air conditioner. A furnace burns fuel or uses electric resistance to create heat. In our climate, a heat pump often heats more efficiently than a furnace until outdoor temperatures drop well below freezing.

Section 2

Efficiency and operating cost

Heat pumps deliver more heat energy than the electricity they consume, which is why their heating efficiency can be 200–300 percent. Electric furnaces are always 100 percent efficient but cost more to run. Gas furnaces are efficient but require gas service and venting.

Section 3

Upstate climate considerations

Greenville and Spartanburg winters are moderate. Most heating demand happens on nights in the 20s and 30s, which is exactly where modern inverter heat pumps excel. Dual-fuel systems, which pair a heat pump with a gas furnace, provide backup heat for the rare extreme cold snap.

Section 4

Which is right for your home

Choose a heat pump if you want one system for both heating and cooling, lower electric bills, and no combustion. Choose a furnace if gas is already piped to the home and you want very fast, high-temperature heat. A dual-fuel system gives you the best of both.
