Heat pump vs Furnace in Charles County, Maryland
When a heat pump makes sense
If your home already heats with electricity, a heat pump makes sense here. It handles both heating and cooling, so you run one system instead of two. Winter nights average 29°F in Charles County, cold enough that you want a cold-climate model rather than a standard one, since standard heat pumps lose heating power in that range.
When a furnace makes sense
If your home is set up for natural gas, a furnace is worth keeping. Gas heat costs at least 15% less to run here than a heat pump, at Maryland prices, and that gap matters over a heating season that runs about seven months. A furnace only heats, so you would still need a separate system for cooling.

If your home already has a gas line and you want the lowest possible heating cost, a furnace still wins.
