Heat pump vs Furnace in Jefferson County, Alabama
When a heat pump makes sense
If you want one system that heats and cools, and you like the idea of lower running costs, a heat pump fits. Winter nights here average 35°F, and a heat pump handles that without trouble. Running on electricity instead of gas costs about 10% less at Alabama prices. If you want the extra margin for colder stretches, a cold-climate model is built to hold its heating power where a standard one starts to lose it.
When a furnace makes sense
If your home already has gas line in and you would rather keep heating and cooling as separate systems, a furnace is the straightforward choice. It only heats, so you would still need a separate air conditioner for summer. Almost half the homes in the county heat with gas, so you would be in good company.
