After 5 years of dealing with other companies without results we finally had someone who knew how to fix our AC. Dan came to the house and diagnosed the problems quickly while explaining everything. He was quick to order parts and come back to fix the issues. He also fixed numerous issues with our boiler system. Dan was on time, polite, explained everything clearly and was a pleasure to deal with every step of the way. I would not hesitate to recommend him for any mechanical work that you may need.
