Nassau County

Western Long Island

From Floral Park to Massapequa, we replace boilers in every Nassau County community. A lot of the homes out here still have their original cast iron steam boilers from the 50s and 60s, and we know those systems inside out.

Central & Eastern Long Island

Our shop is in Melville, so Suffolk County is basically our backyard. We work from Huntington and Babylon all the way out to the East End. Suffolk has more oil heat than Nassau, and we handle oil-to-gas conversions all the time.

Why Long Island Homeowners
Trust Us With Their Boilers

We have been doing this since 1979. That is not a marketing slogan; it is just the truth. When we started out, most of Long Island was heating with oil, and steam systems were the standard in the older neighborhoods. A lot has changed since then. Gas lines have expanded, high-efficiency condensing boilers have entered the market, and homeowners have more options than ever. But one thing has not changed: people on Long Island still need a contractor they can trust to do the job right.

We are a licensed master plumber operation, fully insured, and we pull permits on every single job. That last part matters more than most people realize. A boiler replacement without a permit means no inspection, and no inspection means nobody verified that the work was done safely and to code. We do not cut those corners.

We Replace Every Major Brand

Over the last four decades, we have worked on just about every boiler brand that has ever been popular on Long Island. Whether you have an old Weil-McLain cast iron unit from the 80s, a Burnham that is showing its age, or a Navien wall-hung that needs replacing, we have the experience to handle it. We are factory-trained on these brands and can recommend the right replacement for your home, your budget, and your heating system.

Centrally Located for Fast Response

We are based out of Melville, right off the LIE, which puts us within easy reach of basically any town on the island. Nassau jobs, we are usually there in 30 to 45 minutes. Western and central Suffolk, same thing. Even the North Fork and South Fork are doable when customers need us out there.

For emergency boiler replacements during the heating season, our location gives us a real advantage. We keep common boiler models in stock so we can often get your heat back on the same day or the next morning. When it is January and your boiler just died, that matters a lot more than fancy marketing.

What We Offer Across Long Island

Free Estimates, No Games

We offer free in-home estimates for every boiler replacement job. There is no service call fee, no pressure, and no obligation. A technician will come out, look at your existing system, talk to you about what you need, and give you a written quote. If you want to think it over, no problem. We do not believe in high-pressure sales tactics. Our cost guide gives you a good idea of pricing before we even come out, so there are no surprises.

We also help with financing and make sure you get every National Grid rebate and tax credit you are entitled to. For a lot of families, those rebates make a real difference in what a new boiler costs out of pocket.

Service Area Questions

Common questions from Long Island homeowners about our coverage, availability, and how we work.

Do you serve all of Long Island for boiler replacement?

Yes. We provide boiler replacement services throughout all of Nassau County and Suffolk County. That covers every town, village, and hamlet on Long Island, from the Queens border all the way out to Montauk. We are based in Melville, which is about as central as you can get.

Is there a service call fee for boiler estimates?

No. Our in-home boiler replacement estimates are completely free, with no obligation. There is no trip charge, no service fee, and no pressure to commit on the spot. We come out, look at your system, go over your options, and leave you with a written quote. That is it.

How quickly can you get to my home for a boiler issue?

Being centrally located in Melville gives us fast access to the entire island. For standard estimates, we typically schedule within a few days. For emergency situations during the heating season, we prioritize same-day or next-day response whenever possible. If your heat is out, call us at (631) 860-6681 and we will get there as fast as we can.

What brands of boilers do you replace and install?

We install and service 11 major boiler brands: Weil-McLain, Navien, Burnham, Buderus, Bosch, Peerless, System 2000, Williamson, New Yorker, Green Mountain, and PurePro Advantage. We are factory-trained on these brands and can help you choose the right one for your home and heating system.

Do you handle permits and inspections?

Yes, on every single job. Boiler replacement requires a permit from your local building department in both Nassau and Suffolk County. We handle the entire process: applying for the permit, scheduling the inspection, and making sure everything passes. You should never hire a boiler contractor who skips this step.

Are you licensed and insured?

Yes. We are a licensed master plumber and carry full liability insurance and workers compensation coverage. This protects you as the homeowner. Always ask any contractor you are considering for proof of licensing and insurance before letting them work on your heating system.

Do you do oil-to-gas conversions across all of Long Island?

Yes, we handle oil-to-gas conversions anywhere on Long Island where natural gas service is available. This is especially common in Suffolk County where a lot of homes are still on oil. We coordinate with National Grid on the gas line installation and handle the boiler, piping, and venting work. We can also assist with oil tank decommissioning.
