Heat pump vs Furnace in Cobb County, Georgia
When a heat pump makes sense
If you're also replacing your air conditioner, a heat pump covers both jobs with one machine. Winter nights here average 34°F, mild enough that a cold-climate heat pump keeps up without losing much heating power, and you'll spend about 15% less than a gas furnace to run it at Georgia's prices. It runs on electricity alone, so there's no gas line or gas bill to think about.
When a furnace makes sense
If your home already has gas line, a furnace is the familiar choice, and it's what 68% of homes here use. It only heats, so you'd still need a separate air conditioner for summer. Heat is only needed about 6 months a year here, so the furnace sits unused the rest of the time.
