Heat pump vs Furnace in Blount County, Tennessee

When a heat pump makes sense

If your home already heats with electricity, a heat pump keeps you on the same fuel and gives you cooling from the same equipment. Winter nights here average 31°F, cold enough that a standard heat pump will lose some capacity, so look at a cold-climate model built to hold its output at that temperature. It's the simpler choice for a home with no gas line to begin with.

When a furnace makes sense

If your home already has a gas line, a furnace is worth keeping. Natural gas runs at least 20% cheaper than a heat pump at Tennessee prices, and a furnace holds its full heat output no matter how cold the night gets. You will still need separate air conditioning, since a furnace only heats.
