At 27.37¢ a kilowatt hour against $2.25 a therm, gas is the cheaper way to make heat in Connecticut. A heat pump here costs more to buy and more to run — the case for one has to be something other than money, such as replacing air conditioning at the same time or getting off gas entirely.
One thing these figures leave out
A heat pump cools as well as heats. If your air conditioner is also near the end of its life, you are replacing two machines with one, and the premium above overstates what you would actually spend. That is the situation where a heat pump wins most clearly, and it is worth checking the age of your AC before deciding.
Common questions
How much does a heat pump cost in Connecticut?
Between about $9,800 and $14,800 installed for a 4-ton cold-climate system in a 1,800 square foot home. That is roughly $5,400 more than replacing a gas furnace like for like.
Is a heat pump worth it in Connecticut?
Not on running cost. Gas is cheap enough in Connecticut that a heat pump costs about $358 a year more to run, on top of $5,400 more to install. That is the honest answer at these prices, whatever the equipment is capable of.
Do I need a cold-climate heat pump in Connecticut?
Probably. Connecticut sees around 130 freezing nights a year, which is enough that a standard unit would lean on backup resistance heat often. A cold-climate model holds capacity lower and costs roughly $1,500 more, which is included in the figures above.
