Emergency Boiler Repair in Nassau County
Call for an urgent gas, oil or steam boiler request. Dispatch will review the exact address, boiler type and symptoms, then confirm the current response option—without promising a fixed arrival or first-visit repair.
Call the right emergency service first
An HVAC appointment does not replace 911, the fire department, the gas utility or medical care.
Gas odor or suspected leak
Leave immediately without operating switches or phones inside. From outside, call 911 or National Grid at 1-800-490-0045.
National Grid gas guidanceCO alarm or possible exposure
Move everyone and pets into fresh air, call 911 from outside, and do not re-enter until emergency responders say it is safe.
CDC carbon-monoxide guidanceFire, smoke or active sparking
Leave the area and call 911. Do not wait for an HVAC appointment or try repeated resets.
Dangerous indoor cold
Move vulnerable occupants to a safely heated location and seek medical help for possible hypothermia. Treat the HVAC ETA separately from the safety plan.
CDC hypothermia guidanceReport what you observe
Urgent gas, oil and steam boiler symptoms
Do not open sealed panels, bypass safeties or repeatedly reset a breaker or locked-out system.
Boiler is not heating the home
Report any display code, pressure or temperature reading, and whether radiators or baseboards are cold in every zone or only some.
Water leaking from the boiler
Note where the water appears, whether it is active, and keep clear of water near electrical equipment. Shut off the water supply to the boiler only if you can do so safely.
Loud banging or kettling noises
Banging in steam pipes, gurgling, or a rumbling kettling sound from the boiler can indicate scale, low water or pressure problems. Do not keep resetting a noisy system.
Boiler keeps shutting off or locking out
Repeated lockouts need diagnosis. Repeated resets can conceal a safety fault—share how many times it has shut down and any error code shown.
Steam radiators cold or spitting water
Report whether vents are spitting, radiators are partially warm, or pipes bang when heat starts. These point to vent, pressure or water-level conditions.
Gas odor, smoke or CO alarm
Leave the home first. For gas odor call 911 or National Grid at 1-800-490-0045 from outside; for a CO alarm call 911 from outside. An HVAC visit comes after the safety call.

Boiler-system diagnosis
The visit begins with the reported gas, oil or steam boiler condition and the accessible controls, safeties, burner, pressure and water-level components needed to identify the next step.
The diagnostic is credited toward an approved repair. Dispatch confirms appointment-specific and after-hours terms. Diagnosis, parts, access, equipment condition and authorized scope determine the written repair price.

Never use an oven, charcoal grill or generator to heat indoor space. Move vulnerable occupants to a safely heated location when indoor cold becomes dangerous.
- Keep portable heaters at least three feet from bedding, curtains, furniture and other combustibles.
- Plug an electric space heater directly into a wall outlet—not an extension cord or power strip.
