Best boiler installation pros near Riverhead, 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."

"Great experience !!! 5 stars ! We had an electrician out that quoted us 1500 for a wire repair on our AC. I called out professor pipes and he was able to do the same work for a 1/3 of the price and did a great job. I also had them do a tune up on the system. Went way above and beyond. Honest contractor!! Great service"

"Thank you for your service I was very happy with the change of the thermostat and maintenance of the boiler, it was very punctual and organized in your work I would recommend it without problem, very good work."

"Our well water tested for iron and low ph which was staining our pool and hot tub.  We spent months researching before we settled on using Ken Massa.  Everything was installed in one day and we are very happy with the results.
Before we did this our water had a metallic odor and did not taste very good.  The filtration system that Ken put in changed all that. Ken is a consummate professional who is very knowledgeable and is easy to work with.  We highly recommend Ken Massa and will use him in the future for all our plumbing needs.

"He was very thorough. My refrigerator was not cooling. He figured out the problem and fixed it. It was a major problem and he took his time and was very neat."

"I recommend this company without hesitation. Chris, the technician, and Novis, his assistant, did a wonderful job. They arrived on time, were extremely professional and worked very efficiently. They made sure everything was secured before they started the actual power washing. When the job was completed, they wanted to make sure we were satisfied with the result, which we certainly were. This is a first class company."
