Our reputation has been built one boiler at a time over 45 years. We let our work and our customers speak for themselves.
Detailed testimonials from Long Island homeowners who trusted us with their boiler replacement.
"Our steam boiler was original to the house, installed in 1953. We had been nursing it along for years, but last winter it finally gave out. Domino's came out the next day, measured every radiator in the house, and explained why proper sizing was critical for steam. They installed a new Weil-McLain and the difference is remarkable. Even heat in every room for the first time in years. They clearly know steam systems inside and out."
"We had been wanting to convert from oil to gas for years but the process seemed overwhelming. Domino's handled everything: the National Grid coordination, removing the old oil boiler, installing a Navien condensing unit, and even helped us get the oil tank decommissioned. The whole project took about a week from start to finish. Our first gas bill was significantly lower than what we were paying for oil. Worth every penny."
"I manage a 24-unit apartment building in Hempstead. Our commercial boiler failed in December and I needed someone who could handle a large-scale replacement quickly. Domino's had the new boiler installed in two days with minimal disruption to the tenants. They coordinated the work around building schedules and handled all the permits. Professional from start to finish. They are now our go-to for any boiler work."
"Our boiler died on a Saturday night in January with the temperature in the teens. I called Domino's first thing Sunday morning expecting to leave a voicemail. Instead, someone answered, came out that afternoon to assess the situation, and had a new Burnham installed by Monday evening. They brought space heaters for us to use in the meantime. That kind of service is rare these days. Cannot recommend them enough."
Every boiler we install is done to code, permitted, and inspected. We take pride in clean, professional installations that not only heat your home efficiently but look right when you open the mechanical room door.
With over 5,000 boilers replaced across Long Island, our track record is built on consistently doing the job the right way. That means proper sizing, quality materials, attention to venting and piping, and a thorough cleanup when we leave.
Our 4.6-star rating across 450+ reviews reflects that consistency. We do not cut corners, we do not skip permits, and we do not disappear after the installation. When you work with us, you get a contractor who stands behind every job.

"Replaced our old boiler and water heater with a single Navien combi unit. Freed up so much space in the basement. The installation was clean and they walked us through how everything works."
"No gas on our street so we had to stay with oil. They recommended a System 2000 and our oil usage dropped noticeably the first season. Honest advice, no pressure to oversell."
"Straightforward gas boiler swap. They arrived on time, finished in one day, and left the basement cleaner than they found it. Permit and inspection all handled. This is how it should be done."
"Our 30-year-old boiler was leaking. Got three quotes and Domino's was the most thorough. They replaced zone valves that others did not even mention. No cold spots anymore. Excellent work."
"Converted from oil to a Bosch gas boiler. They managed the whole National Grid process and made it painless. Got a rebate on the new unit too. Very knowledgeable crew."
"Second time using Domino's. Had them replace the steam boiler in our rental property after they did our own home. Same great experience both times. Consistent quality."
"We wanted a premium boiler and they suggested Buderus. Incredibly quiet compared to our old unit. The install was immaculate. Worth paying a bit more for quality that will last."
"Woke up to no heat on a freezing morning. Called Domino's and they were at our house within hours. New boiler was in by the next day. Responsive, professional, and fairly priced."
"My neighbor recommended Domino's after they replaced her boiler last year. Same great experience for us. Fair estimate, showed up when they said they would, and the work is top quality. Will refer them to anyone who asks."
