Best Boiler Contractors in Huntington, NY (2026)
Huntington has one of Long Island's highest concentrations of oil-fired boilers, so the real question here is usually not which boiler but which fuel. A credible contractor prices the conversion honestly, including chimney, tank, and gas-service work, rather than burying it as a surprise later.
What Huntington boiler systems look like
Dominant distribution: Oil-fired hot water and steam, with active oil-to-gas conversion. Because of that, the most useful question to ask any Huntington contractor is how the replacement size was determined and what happens to the existing piping — not which brand they carry.

Housing stock & distribution
Older Huntington housing runs a mix of cast-iron hot water and steam, frequently with an indirect or tankless coil for domestic hot water. Converting to gas changes venting, combustion air, and often the domestic hot-water strategy at the same time. Where gas is not available at the street, a modern oil boiler with a properly matched burner remains a legitimate answer.
Permits, venting & local quirks
Permits go through the Town of Huntington, and Suffolk County Consumer Affairs maintains its own license and complaint records, so verify the entity in Suffolk rather than assuming a Nassau record carries over. Oil-tank abandonment or removal and chimney lining are separate scope items that should each appear with a price.

FAQ — Huntington boiler contractors
Is converting from oil to gas worth it in Huntington?
It depends on gas availability at the street, the total conversion scope, and how long you plan to stay. Ask for one written total that includes the boiler, gas piping, venting or chimney lining, tank abandonment or removal, permits, and any utility charges — then compare that against a modern oil boiler quote.
Does my chimney need a liner with a new boiler?
Frequently yes. Replacing an old atmospheric boiler with modern equipment changes flue gas temperature and volume, and many older masonry chimneys need lining or the equipment needs sidewall venting instead. The proposal should specify which venting method applies and include the work.
How do I check a Huntington boiler contractor's license?
Search the legal business name in Suffolk County Consumer Affairs' license and complaint records, then confirm liability and workers' compensation coverage for the project. Nassau and Suffolk maintain separate systems, so a Nassau listing alone is not confirmation for Suffolk work.
