Heat pump vs Furnace in Beaufort County, South Carolina
When a heat pump makes sense
If your home already heats with electricity, a heat pump keeps that setup and costs about 5% less to run than gas at South Carolina prices. Winter nights here average 42°F, mild enough that a standard heat pump holds its output most of the season. If you want central air too, it does both jobs with one system.
When a furnace makes sense
If your home has a gas line already in place and you would rather keep cooling and heating separate, a furnace is a solid choice. It runs on natural gas alone, so it will not draw on your electric panel during a cold snap. With winter here lasting only about 5 months, you will not lean on it for long stretches of the year.
