Services / Boiler & heating repair

Boiler repair for NYC homes and buildings

A residential boiler in a Brooklyn brownstone, a steam system in a Manhattan high-rise, a commercial boiler in a Queens office building. We diagnose it and aim to fix it right the first time.

We carry parts for all major boiler brands, so many repairs can be finished in a single visit. Whether the boiler is making strange noises, not producing heat, leaking or showing error codes, we’ve seen it.

Questions

Boiler & heating repair: common questions

Why is my boiler not turning on?

Usually a faulty thermostat, low water pressure, a tripped circuit breaker, a pilot light issue on older units, or a failed ignition control. Call us for a same-day diagnosis and we’ll pinpoint the exact cause.

Should I repair my boiler or replace it?

If the boiler is under 15 years old and the repair costs less than half of a new unit, repair is usually the better call. Older units with frequent breakdowns, high energy bills and rising repair costs often make replacement cheaper in the long run.

How much does boiler repair cost in NYC?

It depends on the problem, the parts and the type of boiler, so we don’t quote a number before we’ve seen it. You get a clear estimate before any work begins, with no surprise charges. Estimates on replacements are free.

How often should I have my boiler serviced?

Once a year, ideally before heating season in September or October. Regular tune-ups extend the life of the system and prevent mid-winter breakdowns.

Do you repair apartment building boilers?

Yes. We work on multi-family and apartment building boilers across all five boroughs, and we work efficiently to restore heat for every tenant.

Can you repair a boiler the same day?

In most cases, yes. We offer same-day service for non-emergency repairs, depending on availability in your area, and 24/7 emergency response for no-heat situations.

What boiler brands do you service?

All major brands, including Weil-McLain, Burnham, Peerless, U.S. Boiler Co., Slant/Fin, Crown, Lochinvar and Triangle Tube.
