Boiler Repair & Installation in Brooklyn, NY

Boiler Service Built Around Brooklyn Buildings

A one-pipe steam system from 1925 and a wall-hung condensing boiler from 2022 share one word and almost nothing else. Steam needs the right water line, a clean sight glass, working main vents and a pressuretrol set low, usually under 2 psi. Hot water needs correct pressure, a working expansion tank, bled radiators and circulators that actually move water. Our boiler technicians know both.

Our Boiler Repair Process, Step by Step

1. 1

   Intake. Steam or hot water, symptom, boiler age, arrival window.

2. 2

   Inspection. Burners, ignition, gas valve, low water cutoff, pressuretrol or aquastat, relief valve, circulators, venting and the water line.

3. 3

   Combustion and CO test. Analyzer at the flue, carbon monoxide reading in the boiler room.

4. 4

   Written price. Diagnosis and repair cost before we start.

5. 5

   Repair and run. We fire the boiler, watch it build pressure or temperature, and check that heat actually reaches the far radiators.

Common Boiler Problems We Fix in Brooklyn

No heat. Failed ignitor or thermocouple, a tripped low water cutoff, a stuck gas valve, or a pressuretrol that locked out.

Banging pipes. Water hammer in steam systems from a flooded wet return, a bad pitch on the main, or a boiler running at too high a pressure.

Cold radiators. Clogged air vents on steam radiators, trapped air in hot water loops, or a circulator that quit.

Water on the floor. A leaking relief valve, a cracked section, or a steam boiler that keeps overfilling from a stuck automatic feeder.

Short cycling. A steam boiler with the pressuretrol set too high, or a hot water boiler with a waterlogged expansion tank.

Rusty water in the sight glass. Surging from dirty water. The boiler needs skimming.

Boiler Installation & Replacement

Steam boiler replacement. Sized to the connected radiation in EDR, not to the old boiler, with new near-boiler piping done to the manufacturer's drawing so the steam leaves dry.

Hot water boiler replacement. Cast iron or high-efficiency condensing, with a new expansion tank, circulators and zone valves where the old ones are tired.

Combi and wall-hung boilers. Heat and domestic hot water from one unit, for smaller houses and renovated condos.

Oil to gas conversions. Burner swap or full replacement, chimney liner, Con Edison coordination.

Every replacement includes DOB filings and inspection, and a combustion report at the end.

What Affects the Cost of Boiler Work in Brooklyn

Repair or replace. A thermocouple or an air vent is a small fix. A cracked section on a 30-year-old boiler is not worth repairing.

Steam or hot water. Steam replacements take more piping and more labor.

Chimney and venting. A liner for a chimney that used to share with an oil burner, or sidewall venting for a condensing boiler.

Size. A six-unit building with 40 radiators is a bigger job than a one-family.

Permits. DOB and gas inspection fees as line items.

Local Conditions We Work Around in Brooklyn, NY

One-pipe steam. The borough is full of it. Pitch, venting and water line matter more than the boiler brand.

Flooded basements. Boilers set on pads, electronics above the historic water line.

Orphaned water heaters. A water heater left alone on a chimney after a boiler swap backdrafts. We check.
