They do. It's not as good as the MA program but look at the cl&p website or Yankee if that's your provider. Look for the home energy audit. They replace all your bulbs and do a blower door test then spend a few hours sealing up leaks. You also get a written report with recommendations and having do e this you can qualify for the special low or no interest loans through chif.org Course my house had the equivalent of 3000 basketballs flying out the door in an hour in terms of heat loss. I need $10k in insulation and sealing. Sigh.
