Heat pump vs Furnace in Greenville County, South Carolina
When a heat pump makes sense
If your house already heats with electricity, a heat pump fits right in, and it costs about 5% less to run here than a gas furnace does. Winter nights average 34°F, cold enough to matter but not the deep freeze that a cold-climate heat pump can't handle. It also cools your house in summer, so one system covers both jobs instead of pairing a furnace with a separate air conditioner.
When a furnace makes sense
If your house already has a gas line run to it, a furnace is worth keeping. It only heats, so you would still need a separate air conditioner for summer, and a standard heat pump can lose heating power on the coldest nights in a way a furnace does not. With homes here needing heat about 7 months of the year, that steady output counts for something.
