Boiler & Radiator Heat Repair

Boilers heat the home with hot water or steam through radiators or radiant floors. When a boiler goes down in winter, the whole house—or the whole building—goes cold quickly.

Call: 1 (800) 555-0199

Warning signs

Radiators stay cold
Low pressure on the boiler gauge or a leaking relief valve
Banging or kettling noises
Water leaking around the boiler
Pilot light keeps going out

What to do right now

Check the thermostat, power switch and breaker
Note the pressure reading on the gauge for the technician
Don't add water or bleed radiators on a steam system unless you know how
If you smell gas or a CO alarm sounds, leave immediately and call 911

What the HVAC technician will do

A technician will check the burner, ignition, circulator pump, expansion tank, low-water cutoff and controls, and inspect venting before restarting.

What affects the cost

Pumps, valves and controls are mid-range repairs; heat exchanger failures often mean replacement. Older boilers may need hard-to-find parts. Pricing is set by the independent provider—ask for the trip charge and an estimate before work begins.

Safety first

Carbon monoxide alarm sounding? Get everyone outside and call 911.
Smell gas? Leave now and call your gas utility or 911 from outside. Don't flip switches.
Dangerous heat or cold in your home? Don't wait for a repair—go somewhere safe and check on vulnerable family and neighbors.
