Heat pump vs Furnace in Hardin County, Kentucky
When a heat pump makes sense
If your home already heats with electricity, a heat pump is the straightforward choice, since it cools in summer too and you are not paying to run a second fuel line. Winter nights here average 27°F, so look for a cold-climate model built to hold its heating power at those temperatures rather than a standard unit that loses capacity as it drops.
When a furnace makes sense
If your home already has gas heat, keeping the furnace makes sense. It costs at least 5% less to run than a heat pump at Kentucky prices, and a furnace does not lose heating power as the temperature drops. You would still need a separate air conditioner for summer, since a furnace only heats.

Heat pump wins in Hardin County.
