Heat pump vs Furnace in Suffolk County, New York
When a heat pump makes sense
A heat pump makes sense if you want cooling and heat from one system and don't already have gas line access. It will still heat your home when nights drop to 26°F, but a cold-climate model is the one to ask for, since standard models lose heating power in that kind of cold. Weigh the electric running cost against what you're paying now before you decide.
When a furnace makes sense
A furnace is the better fit if your home already has a gas line, since natural gas costs at least 35% less to heat with here than a heat pump does. With 8 months of heating season and winter nights averaging 26°F, that difference adds up. You will need a separate air conditioner for summer, since a furnace only heats.

Furnace wins in Suffolk County.
Gas heat runs at least 35% cheaper than a heat pump at New York prices, and with 8 months of heating a year here, that adds up fast.
If you want one system that heats and cools instead of running a furnace alongside a separate air conditioner, a cold-climate heat pump is still worth a look.
