"Moved heavy boiler up difficult site. Installed in one day. Very professional and patient in detailed explanations of complex zoning issues. Prices are high in Dutchess Co. compared to other areas of NY. I generally think plumbers are a safer bet for a maintenance plan and longer lasting businesses than most HVAC companies."

"Scott and his apprentice were excellent. I would highly recommend his service. He is very professional and punctual. They installed two ceiling fans in my bedrooms. My master bedroom didn’t have attic access and he was able to think outside the box and install the fan. His price was very reasonable and he did superb work. Thanks Scott!!! Any electrical work I will need in the future, I’ll be calling Scott!!!"
