Get matched with top boiler installation pros in Patchogue, 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."

"The boiler pressure relief valve was leaking, so it was determined that replacing the boiler expansion tank and pressure relief valve caused the temperature controller to malfunction, and the temperature controller was replaced as well. The water heater expansion tank was also replaced due to a leaking connection.. The total repairs expense is $775. The apoointmebt time was 9:00 am, they came in around 10:30."

"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."

"Billy and his crew were an absolutely pleasure to work with. They exceeded my expectation to replace my boiler and hot water heater along with associated piping in record time working in concert with the GC to complete all work in 3 days. The finished work was neat and clean correcting errors with my original installation. All debris was removed each day. He ensured I was satisfied, kept me informed of the progress and what to expect. Upon leaving he made recommendations to have all my air valves replaced in my radiators and encouraged me to call with any questions. I appreciate the care he and his crew took with my home."

"Had an excellent experience. He replaced my boiler and water heater and did a flawless job from start to finish. Super professional, showed up on time, explained everything clearly, and the work was clean and efficient. The new system runs perfectly, and the installation looks great.
