When we opened our doors in 1988, our goal was simple – to offer the Connecticut residents the best heating and air-conditioning service and installation, paired with unparalleled customer service. More than 32 years later, it’s still our goal – and something we work at every day. Lots of businesses can be licensed and trained, but not everyone builds trust, values long-term relationships, and provides quality work.

(Plus, we’re rated A+ by the Better Business Bureau.)

A Trane Dealer since our first day in business

We’ve been proudly installing Trane products since day one. Then in 1999, we achieved Trane Comfort Specialist status, a designation we still maintain. It’s one more assurance of a higher level of skill, knowledge, quality, and your ultimate satisfaction.
