I live in an older building, and while it has its charms those charms make for some unique challenges. The whole team at ThermEnergy took those challenges in stride and found solutions to things none of us were expecting to encounter. They were professional, tidy, on time and did all that challenging work with a smile. Beyond that, despite encountering some challenges that no one expected they were very fair about their pricing and frankly very reasonable particularly considering the quality and care they placed in their work. I will absolutely be recommending them to all of my friends and family, they do great work!
