Heat pump vs Furnace in Nassau County, New York
When a heat pump makes sense
A heat pump makes sense if you want cooling and heating from one system and you're set on getting off gas. Look for a cold-climate model, since standard heat pumps lose heating power once temperatures drop toward 28°F, which is a normal winter night here. Weigh the higher running cost against what you value in going electric, since gas heat costs at least 35% less at New York prices.
When a furnace makes sense
A furnace fits most homes in Nassau County, and 62% already heat with gas for a reason. It costs less to run than a heat pump here, and it keeps its full output no matter how cold the night gets outside. The tradeoff is that it only heats, so you would still need a separate system for cooling.
