Heat pump vs Furnace in Chatham County, Georgia
When a heat pump makes sense
If your home is on electric service already, a heat pump is the straightforward choice. Winter nights here average 42°F, which is mild enough that a standard heat pump keeps up without much strain, and you get cooling from the same system come summer. At Georgia electric rates, it costs about 15% less to run than a gas furnace through a winter that only lasts about five months here.
When a furnace makes sense
If your home already has a gas line and you'd rather keep a separate system for cooling, a furnace still makes sense. It runs on natural gas alone, so it won't touch your electric bill for heat, and it will outperform a standard heat pump if you get the rare hard freeze. It only heats, so you'd still need a separate air conditioner for summer.
