“We recently had an energy audit done by Mike and were beyond impressed with his knowledge and expertise. Based on the outcome, we had new insulation put in our attic and both the garage and basement sealed. I can’t say enough good things about Mike and the team at Mainline. They were extremely quick and efficient. I definitely recommend them!”

Ashleigh J., Coventry CT

“We had a cleaning, and Sacha replaced one part on warranty. Thank you, Sacha, you did a great job. There was no mess at all, very clean.”

Phil L., Coventry CT

“We had ductless heating/air conditioning units installed in 4 rooms, had the house sealed and re-insulated the attic and parts of the basement. Mike was very down to earth, and all his recommendations made sense to us. The house feels great – better than it ever has before. Consistent heat, no drafts and lower monthly bills. We talked about going solar, but this made more sense to us. Mike and the team made sure we were 100% satisfied with their work. I would recommend them to others. We chose this company by doing internet research on Fujitsu, and when I looked for local installers we found Mainline.”
