Why NYC Boilers Fail, and How We Fix Them
These are the calls we see every heating season.
- LockoutsThe boiler shuts itself down as a safety measure: a dirty flame sensor, low water, ignition failure or a gas valve problem. We find the cause instead of just resetting it.
- Ignition failureThe burner won't light, or lights and shuts off after a few seconds. Often a dirty sensor or failed igniter, and usually preventable with yearly service.
- Pressure droppingOn hot-water systems: a leak, a failing relief valve or an expansion tank problem.
- Banging pipesWater hammer in steam systems. What boiler noises mean →
- Cold radiators, uneven heatFailed air vents or steam traps, unbalanced risers, or air trapped in a hot-water system.
- Skipped maintenanceThe most common root cause of all. A boiler that's never serviced tends to fail on the coldest night of the year.
Residential & Commercial Boiler Service
From one-family homes to apartment buildings and businesses.
Boiler Repair
Emergency and scheduled repairs on steam and hot-water boilers: burners, ignition, controls, low-water cutoffs, valves and safety devices.
Annual Tune-Up
Cleaning, inspection, safety checks and combustion analysis with a digital analyzer, before the heating season starts.
Steam Systems
Air vents, main vents, steam traps, Hartford loops, pressure controls and pipe pitch, on one-pipe and two-pipe systems.
Hot-Water Systems
Circulator pumps, zone valves, expansion tanks, air removal, radiant heat and the condensate neutralizers on high-efficiency boilers.
Boiler Replacement
When repair stops making sense, we show you why in writing and size the new boiler to your building, not the old nameplate.
Heat Pump Alternative
Facing a replacement? Compare it with a heat pump and Con Edison Clean Heat rebates. See heat pumps →
Apartment Buildings and Co-ops
In a building with one boiler, uneven heat between apartments and banging pipes are usually distribution problems: failed steam traps, poor venting or unbalanced risers. Replacing the boiler won't fix them. Fixing the distribution will, and it usually costs far less.
NYC heat season runs October 1 to May 31: at least 68°F indoors from 6am to 10pm when it's below 55°F outside, and at least 62°F overnight. When a building boiler goes down, call us first. We work with supers and managing agents, and provide a certificate of insurance (COI) on request.

NYC Boiler FAQ
Why does my boiler keep locking out?
A lockout is a safety response: the boiler detected a problem and shut itself down. Common causes are a dirty flame sensor, low water, ignition failure or a faulty gas valve. Pressing reset over and over doesn't fix the cause. We find it so the problem doesn't come back.
What is combustion analysis?
A test with a digital analyzer that measures how well your boiler burns fuel and checks for dangerous conditions like high carbon monoxide. We include it in our annual tune-up.
Do you service steam and hot-water boilers?
Yes: one-pipe and two-pipe steam, hot-water systems with radiators or baseboard, and radiant heat. We service most residential and commercial boiler brands.
What is a condensate neutralizer, and does mine need service?
High-efficiency (condensing) boilers produce acidic water. A neutralizer treats it before it goes down the drain. The neutralizing media wears out and should be checked during yearly service and replaced when it's used up. A clogged neutralizer can back up and shut the boiler down.
Should I repair or replace my boiler?
Repair first, whenever it makes sense. If the boiler is old, keeps failing, or a repair would cost a large share of a new one, replacement may be the better choice. We'll put the numbers in writing so you can decide, including a heat pump option with Con Edison rebates if it fits your building.
How often should a boiler be serviced?
Once a year, ideally before the heating season. Our 5-Star Membership includes two tune-ups a year, priority dispatch and 10% off repairs.
