Get matched with top boiler installation pros in Mastic Beach, 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."

"Tom was terrific....repaired boiler....cost reasonable.....explained everything so clearly so that even this 88year old understood it....experience with company from start to finish was a pleasure"

"Extremely satisfied & pleased with the work performed by Elm. Eric, Rob & Jesse were great on the installation – on time, neat, careful to show us the status as they went through the job. Have already recommended Elm to neighbors who expressed interest. Scott was great on the initial review & estimate & Cathy in the office was extremely helpful as well. Thank you to the whole Elm Team!"

"Vinny and his son are top notch. Punctual, honest, dependable, and most importantly they do a good job. They stand behind the product and their work and supports you for the long term. They have never not answered a phone call or text. Vinny has installed multiple mini splits at our house, comes yearly for the service, and has fixed our boiler. I would highly recommend them to anyone."

"It went very well!! The steam cleaning really gets rid of all the dust, grime and dirt that accumulates over time. It gets into all the nooks and crannies that you would need a toothbrush or toothpick to get clean. I feel like my house has never been this clean, and floors have never been this shiny. I would highly recommend them - extremely professional and takes pride in their work."
