Heat pump vs Furnace in Northwest Hills Planning Region, Connecticut

When a heat pump makes sense

If your home already has gas service and you mainly want cooling, a cold-climate heat pump can cover most of the year and let the furnace take over on the coldest nights. Standard heat pumps lose heating power as it drops toward the teens, and nights here average 17°F from December through February, so only the cold-climate models keep up. Without gas at your house, a cold-climate heat pump is still worth weighing, but with heat needed about eight months a year, plan on it working hard.

When a furnace makes sense

With nights averaging 17°F from December through February and heat needed about eight months of the year, a furnace is built for how much this house has to run. Natural gas costs at least 45% less than a heat pump to heat with at Connecticut prices, and that gap matters over a season this long. A furnace only heats, so cooling means a separate system, but if gas already runs to your house, it is the steadier choice for winter here.
