Boiler Repair on Long Island

Most boiler repairs on Long Island cost between $200 and $900 depending on the issue. Common fixes like a circulator pump replacement run $400-$700. Ignition, aquastat, or thermocouple replacements are usually $200-$450. A full boiler replacement is a separate conversation, and we'll give you a written repair quote before any work begins. If replacement makes more sense, we'll lay out that option with rebate pricing too.

As a general rule, if your boiler is over 15 years old and the repair costs more than 40% of a replacement, replacement is the smarter move. Older oil boilers in particular lose efficiency every year, and a modern high-efficiency gas boiler or an oil-to-heat-pump conversion will pay back the difference in a few winters. We always price both options so you can decide with the full picture.

Yes. Long Island has thousands of legacy oil-fired boilers, and we service them regularly. Common oil boiler repairs include nozzle replacements, oil burner cleanings, flame retention head adjustments, and aquastat replacements. If your oil boiler is near end-of-life, we can also walk you through whether a PSEG and NYSERDA rebated oil-to-heat-pump conversion makes more sense than another repair.

Yes. We service gas-fired boilers from most major brands including Weil-McLain, Burnham, Buderus, Lochinvar, Navien, and Peerless. Common gas boiler repairs include gas valve replacements, pressure switch issues, ignition failures, and flame sensor cleanings. We carry common parts on the truck so most repairs finish in one visit.

A well-maintained boiler on Long Island typically lasts 15-25 years. Oil boilers tend to fall on the lower end of that range because oil combustion is harder on the equipment. Salt air in the southern coastal communities can also shorten the lifespan of copper and cast iron components. Annual service makes a meaningful difference, and we offer maintenance plans that include a full boiler tune-up.

The most common causes of a boiler losing pressure are a leak in the system (baseboards, pipe fittings, a failed pressure relief valve), a waterlogged expansion tank, or a failing auto-fill valve. Repeatedly adding water to keep pressure up is a sign something is leaking, and running a low-pressure boiler can damage the heat exchanger. Call us sooner rather than later.

For most Long Island homeowners, yes. The PSEG Long Island, NYSERDA, and federal IRA rebates for oil-to-heat-pump conversions typically stack to $7,000-$10,000 or more, which makes the out-of-pocket cost competitive with a like-for-like boiler replacement. You also cut heating costs roughly in half and get whole-home air conditioning included. We explain the full math on our oil-to-electric page.
