Heat pump vs Furnace in Montgomery County, Tennessee
When a heat pump makes sense
If your house already heats with electricity, a heat pump is the natural fit, since you keep the same setup you have now. Winter nights here average 30°F, cold but not extreme, and a cold-climate model holds its heating power on those nights when a standard model would start to lose it. You also get cooling in summer from the same unit.
When a furnace makes sense
If your house already has gas heat, running cost favors staying with it. Gas heat costs at least 20% less to run than a heat pump at Tennessee prices, and that gap adds up over the 7 months a year your house needs heat. A furnace only heats, so you would still need a separate air conditioner for summer.
