Heat pump vs Furnace in Limestone County, Alabama
When a heat pump makes sense
If your home already heats with electricity, a heat pump is the natural fit. Winter nights here average 33°F, which is well within range for a heat pump to work efficiently, and a cold-climate model will keep its output on the coldest nights of the year. You also get cooling from the same unit, and at Alabama's electric rates it costs about 10% less to run than gas heat.
When a furnace makes sense
A furnace makes sense if your home is already piped for natural gas and you'd rather keep a gas system in place. It only heats, so you would still need a separate air conditioner for summer. Gas heat costs a bit more to run here than a heat pump, but for a home already set up for it, that may not outweigh sticking with what's there.

Heat pump wins in Limestone County.
Most homes here already run on electric heat, and with winter lows only dipping to 33°F, a heat pump handles it without strain.
If your home already has a gas line and you'd rather not depend on a heat pump's output on the coldest nights, a furnace is still worth choosing.
