Boiler or radiators not heating? Repairs in Syracuse, $100 off
Across New York, New Jersey and Pennsylvania, steam and hot water heat is almost four times as common as nationally. The repairs differ from a furnace's. Pick the boiler repair on the form. A local contractor takes it from there.

Gas smell or CO alarm? Leave first.
Smell gas or hear a carbon monoxide alarm? Get everyone outside into fresh air first. Once outdoors, call 911 or the gas utility. Do not go back in to restart a boiler. Never run a system that a safety control shut off.
Signs this is the repair you need
Radiators cold at the top or all over
Air in the system, a stuck valve or a pump that has stopped can each leave the radiators lukewarm.
Banging, knocking or gurgling
Water hammer in steam, trapped air in hot water, or a pump bearing starting to fail all make noise.
The boiler runs but the house stays cold
Heat is made and not delivered. The circulator or a zone valve is the first suspect.
Boiler locks out or shuts down
A low water cutoff, a safety control or an ignition fault can stop the boiler and keep it stopped.
Water on the floor or a drip from a fitting
Leaks are not a wait-and-see problem near a boiler. Switch the system off and send the form.
Questions people ask first
Why are my radiators cold at the top?
Usually trapped air. Use a radiator key to open the bleed valve (hot water radiators; steam radiators vent themselves), with a towel ready. If it fills with air again quickly, a contractor should look at the system's air removal.
Is a banging boiler dangerous?
It is a sign something is wrong, not always a danger. A knock that comes with a lockout, a leak or a smell means switch it off and call for the repair.
Should I add water to the boiler myself?
Do not guess. A falling water level can mean a leak, and a boiler fed blindly can be damaged. Ask the contractor what pressure the system should hold.
Do you handle steam and hot water?
We connect you with a contractor. Tell them which type you have when they call, because older houses in this region often have one or the other.
What moves the price
- Pump, valve or control: which one failed
- Whether the boiler room is easy to reach and the parts are in stock for an older make
- Whether the system must be drained and refilled
- A leak in a fitting or radiator that must be fixed before the heat can be restored

What it usually turns out to be
Some of these are cheap. That is worth knowing before you book.
Circulator pump
The pump moves hot water through the loops. A seized or worn circulator is among the most common reasons a boiler heats and the radiators stay cold.
Expansion tank
A waterlogged tank cannot absorb pressure swings, so the relief valve weeps and the pressure keeps climbing. Replacing the tank is usually a contained repair.
Air in the radiators
Trapped air leaves the top of a radiator cold. Bleeding the vents, or fixing the air separator that should be catching it, restores the flow.
Low water cutoff
This control stops the boiler when the water level drops too far. It is a safety device, so a lockout means find out why the level fell, not bypass it.
How the visit runs
Walk the system
The contractor follows the heat from boiler to radiators, noting which rooms are cold and what the pressure gauge reads.
Test the weak link
Pump, valves, controls and the cutoff are checked in turn, so the part you pay for is the one that failed.
Agree the repair
You get the fault and the cost before work starts. Ask about cleaning or flushing only if the contractor can explain why it is needed.
Refire and balance
After the repair, the boiler is brought up to temperature and the radiators checked for even heat.
The fact that changes this repair
New York requires carbon monoxide alarms in homes with fuel-burning appliances, and the Fire Code asks for detection in the rooms and sleeping areas that contain one. Check that your alarms work before a boiler repair, not after.
