In Manhattan, a boiler that has stopped heating is usually one of two situations. In a small building or townhouse, it is a single boiler with a single owner who needs it fixed today. In a co-op, condo or doorman building, it is a central boiler serving many apartments, and the repair has to be coordinated with the super, the managing agent or the board. We repair steam and hot-water boilers in both, and we start by identifying which system you have and what the boiler is actually doing.

Many pre-war buildings heat with a central steam or hot-water boiler. A single failure can leave every apartment cold, so no-heat calls are treated as urgent and coordinated with building staff.
Larger buildings often run more complex central systems with multiple boilers and controls. We tell you plainly what we can work on and what needs the original installer.
Townhouses typically have their own boiler. Repair or replacement decisions come down to the unit's age, condition and what has failed.
Working in Manhattan has its own logistics. Loading and access rules, freight elevators, building management and co-op boards can all affect how and when work happens. Tell us the building type and whether a super is on site when you call, and we will plan around it instead of discovering it on arrival.
A boiler problem is often discovered at the worst moment: the first cold week, a holiday, a night. If your building has a central boiler, report the problem to management as well, because they may need to coordinate with other residents while repairs happen.
A co-op on the Upper West Side loses heat on a January morning. The super reports the boiler has locked out. In a building like that, the first questions are whether the boiler is getting fuel, whether water level and pressure are correct, and whether a safety control has tripped. A townhouse in the Village with its own boiler is a different job: one owner, one system, one decision about repair or replacement. We handle both, and in the first case we work with the building staff on access and timing.
These are illustrations of the kinds of problems we are asked about, not case studies.
A boiler that is not heating has either lost its call for heat, lost a safety condition, or lost the ability to move heat. On a gas boiler, a pilot that will not stay lit often points to a failed thermocouple or flame sensor. A hot-water boiler can stop heating because of low pressure, trapped air or a circulator that is not running. A steam boiler can shut down because of low water or a control problem. These look the same from your living room, which is why we diagnose before we recommend.
If the boiler is running but a radiator is cold, the problem may be at the radiator and not the boiler. See radiator repair in Manhattan for valves, vents and leaks.
A single failed part on an otherwise sound boiler is usually worth repairing. Repeated failures, leaks from the boiler body, heavy corrosion or very old age point toward replacement. In Manhattan, replacement scope depends on whether the new boiler goes in the same place with compatible venting, or needs to be resized or relocated. Gas boiler work is performed by or under the supervision of a licensed plumber, and installation is quoted separately from repair.
Steam heating problems are common in older buildings: radiators that bang, rooms that never warm, hissing or spitting vents, and boilers that shut off from low water. Steam boilers depend on the correct water level, working low-water cutoff controls and radiators that vent properly. We tell you plainly whether the problem is at the boiler, the vents or the piping.
If one radiator is the only issue, see radiator repair in Manhattan.
A pre-season check looks at pressure or water level, ignition, controls and visible leaks. It is easier to fix a small issue in October than to respond to an emergency in January, when every plumber in the city is getting the same call. If your boiler is old, this is also the time to ask whether it is worth repairing or planning to replace.
Tell us the building type, the age of the boiler if you know it, and what you have noticed. An honest answer about repair versus replacement is part of the visit.
A single failed part, such as a thermocouple, circulator or relief valve, is usually a contained repair. Age and condition matter: an older boiler with corrosion or several worn parts is more likely to need a broader repair. System type matters too, because steam and hot-water boilers fail in different places. Replacement scope depends on venting, gas, size and access, and we explain it before work begins.
