Steam & Hot-Water
Boiler Systems.

Common Boiler
Problems We Fix.

Two Different
Systems.

A boiler and a water heater are genuinely not the same thing, though they're commonly confused with one another. A boiler heats water or steam that runs through radiators or baseboard units to heat your living space. A water heater supplies hot water to your faucets, shower, and appliances. Some buildings run a single unit that does both jobs at once; many others have them set up as entirely separate systems.

If your issue is no hot water at the tap rather than no heat in the rooms, that's more likely a water heater problem, not a boiler one. Tell us what's actually happening when you call and we'll point you to the right diagnosis.

What These Boiler
Problems Actually Mean.

Banging or knocking radiators in a steam system usually means trapped water hitting rising steam as it moves through the pipes, often caused by a pitch or drainage issue somewhere in the piping itself rather than the boiler unit. Low pressure warnings on a hot-water system often point to a leak somewhere in the closed system, even a genuinely small one, or air that's worked its way into the lines and needs to be properly bled out. Pilot light or ignition issues on a gas boiler can be a simple relight or something more involved like a failed thermocouple or ignition control board.

Inconsistent heat — some rooms comfortably warm, others noticeably cold — often points to an air-lock or a balancing issue somewhere in the distribution system, rather than the boiler itself failing outright. A boiler leaking water needs prompt attention regardless of how minor it looks, since even a small leak indicates a seal, valve, or pressure relief issue that tends to get worse, not better, over time.

Boiler Checks
Before Winter.

The best time to have a boiler properly checked is well before heating season actually starts, not during the very first cold snap when every plumber across the city is getting the same call at once. A pre-season check typically covers system pressure, pilot or ignition function, and a visual inspection for leaks or corrosion — catching a small issue back in October is a much smaller and cheaper job than an emergency no-heat call in the middle of January.

If your boiler is old enough that you're not sure how many more winters it has in it, that's worth a conversation too. We'll give you an honest read on whether it's worth continuing to repair or whether replacement makes more sense given the unit's age and condition.

What Affects Boiler
Repair Scope.

A single failed part — a circulator pump, a pressure relief valve, an ignition control board — is generally a fairly straightforward repair once it's been diagnosed correctly and confirmed as the actual cause. Age and overall condition matter quite a bit too: an older boiler already showing corrosion or several aging components at once is more likely to need a broader repair, or to reveal a second underlying issue once the first is fixed, compared to a newer unit with just one isolated failure.

System type affects the job as well, and meaningfully so. Steam systems have their own distinct set of common failure points — steam traps, vents, water level controls — quite different from what typically fails on a hot-water hydronic system instead. Installation scope depends heavily on whether you're simply replacing an existing boiler in the same location with similar venting already in place, versus relocating the unit or upsizing capacity, which can involve considerably more significant venting and gas line work as part of the job.

Our Boiler Repair
Process.

Central Boilers &
Building Coordination.

A central boiler serving a multi-unit building affects heat for every connected apartment in the building, not just one household — which genuinely changes how the job needs to get scheduled. We coordinate timing directly with building management or a super rather than a single occupant, and communicate clearly and honestly about how long heat will realistically be affected during the repair.

If you don't know whether your building has a central system or individual units, that's fine — tell us your building type when you call and we'll help figure out what applies.
