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) 555-0199Warning 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.
