Excellent from day 1. The owner came to our home in a Saturday for an estimate. He was the only contractor who told us about the CT heat loan. We got the loan and from them they were out less than a week to install our Mitsubishi unit with 4 heads. The whole thing was seamless from start to end. Excellent technicians, Andrew DePallo and Alex Dionne. They were knowledgeable, friendly and communicative. They did NOT take any shortcuts. Obviously they take pride in their work. I am definitely going to use their services again. OUTSTANDING.
