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.

How much does a heat pump cost in Maine?
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.

Do I need a cold-climate heat pump in Maine?

Whether panels pay off
