Get matched with top boiler installation pros in Setauket, NY

"I was very happy with my experience using this company. In the middle of a heat wave, right before the July 4th holiday, my AC stopped working. The man who installed it and had been servicing it was too busy to come for a week. I called MSD and was given an appointment for 8 AM the next morning. They were prompt and courteous, fixed my problem, and were reasonably priced. I will be calling them in the future."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"Vincent, the technician, arrived wearing a mask (pandemic times), observed social distancing, and was skillful and quick at performing the job. He took the time to explain the new thermostats to me and set them for me after I requested it. He cleaned up, left no mess. NH Ross installed my new boiler which is working great!"

"I hired Joe from MassAir to install Central Air in our home recently. From the start he answered all my questions, always returned my calls quickly, and gave a fair price. He explained exactly what they would be doing and how long it would take, and he and his workers were professional and courteous. They did the job quickly, cleaned up after themselves, and all around provided everything he promised. Overall we are very happy with the work they did, and I would highly recommend MassAir for air conditioning work."
