Heat pump vs Furnace in Capitol Planning Region, Connecticut
When a heat pump makes sense
A heat pump makes sense if you want cooling as well as heat from one system, or if you don't have a gas line to the house. Pick a cold-climate model, since standard ones lose heating power on nights this cold, and expect the electric rate to run at least 45% higher than gas here.
When a furnace makes sense
A furnace is the right call for most homes here, where winter nights average 21°F and heat is needed about eight months of the year. It runs on natural gas, costs at least 45% less to run than a heat pump at Connecticut rates, and holds its output no matter how cold it gets outside. You will need a separate air conditioner for summer, since a furnace only heats.

Furnace wins in Capitol Planning Region.
Gas costs at least 45% less than a heat pump here, and with winters this cold that difference shows up on every bill.
If your home has no gas line to tap into, a cold-climate heat pump will still get you through a 21°F night, and you'd gain cooling as well.
