Boiler Repair & Installation
in Suffolk County, NY

If you’re out of heat, have uneven radiators, or need a boiler replaced, I diagnose the issue and get the system heating again. I install, service, and repair gas and oil boilers — both hot-water (hydronic) and steam — for homes and light commercial buildings.

Boiler repair when the heat isn’t keeping up

A boiler with neat piping

A weak boiler shows up quickly once the weather turns — no heat, cold rooms, knocking pipes, leaks, or radiators that never quite get hot. I’ll inspect the boiler and the system it feeds, explain what I find, and recommend a repair when that’s the sensible path.

I also do this work for light commercial spaces, not just houses. If the job is bigger than I should take on, I’ll tell you rather than overpromise.

If the boiler is at the end of its useful life, or a repair would cost more than it should, I’ll walk you through a replacement with a clear estimate and no hard sell. I handle the work myself, start to finish.

Steam and hot-water heat in older Long Island homes

A warm living room in an older Long Island home

Plenty of homes on the North Shore and in the older parts of central Suffolk still heat with a boiler, radiators, or baseboard hot water — gas or oil. That’s normal here, especially in houses that weren’t built around a forced-air furnace. I work on both hot-water (hydronic) and steam systems, and I’ll be honest about what your particular setup needs.

Financing is available — ask when you call.

If your house has a gas furnace instead of a boiler, or you’re looking at a heat pump, I can help with those too. I’ll recommend the system that fits the home, not a one-size pitch.
