Boiler Not Heating in Thornwood, NY

When the boiler runs but the house stays cold, the problem is usually on the water side. When the boiler is silent, it is usually power, gas or ignition.

Start with the easy checks. Is the thermostat calling for heat, with fresh batteries? Is the service switch at the top of the basement stairs on? Is the pressure gauge in the normal range, around 12 to 15 psi on most hot water systems? A low reading can trip the low-water cutoff and stop the burner.

Reliable Boiler Service connects Thornwood, NY homeowners with technicians who trace the rest: a circulator that hums but does not spin, a zone valve stuck closed, air trapped at the high point of a loop, or one cold zone that points to a thermostat wire.

If only the upstairs is cold, air in the system is the likely cause. If every zone is cold, look at the boiler itself.

Call Reliable Boiler Service at (866) 456-6311 when your boiler is not heating.

Boiler Not Heating FAQs

Frequently asked questions about Boiler Not Heating

Questions we hear most often about Boiler Not Heating in Thornwood, NY.

Talk to a real person
Is a combi boiler a good fit for my home in Thornwood, NY?
A combi suits homes with one or two bathrooms and a gas line big enough for its hot water demand. Larger households often do better with a heat-only boiler and an indirect tank.
Do condensing boilers work with old cast iron radiators?
They can, but they only condense when return water comes back cool. Outdoor reset control and properly sized radiators make the difference.
How often should a boiler be serviced?
Once a year, ideally before the heating season. Steam boilers with a float type low-water cutoff also need regular blowdown through the winter.
My boiler is running but the house is cold. What should I check?
Look at the pressure gauge, listen for the circulator pump, and feel the pipes leaving the boiler. Hot boiler with cold pipes usually means a pump or zone valve problem.
Do you handle steam boilers in older buildings?
Yes. Reliable Boiler Service connects owners with technicians who work on one-pipe and two-pipe steam, including air vents, pressuretrols, sight glasses and low-water cutoffs.
