Gas Fired Boiler Repair in Yonkers, NY
No heat, noisy pipes, or a lockout — we get your gas boiler back online.
When a gas boiler stops producing heat, it's usually an igniter, thermocouple, circulator, control, or pressure issue. Gas fired boiler repair diagnoses and fixes the problem quickly.
Diagnosing a boiler that won't heat
A gas boiler that isn't producing heat usually fails in one of a few ways: it won't light, it lights and shuts off, it runs but the heat doesn't reach the radiators, or it's leaking or losing pressure. Each points to different components. Ignition problems may involve the igniter, flame sensor, gas valve, or pilot assembly. Short cycling can come from a failing sensor or control. Heat that doesn't reach radiators often traces to a circulator pump, zone valve, or air in the system.
We test methodically to find the actual failed component instead of replacing parts until the problem goes away.
When repair makes sense — and when it doesn't
Many boiler problems are straightforward repairs that restore years of service. But if a boiler is very old, has a cracked heat exchanger or section, or needs repeated repairs, replacement may be more economical. A cracked heat exchanger can also pose safety risks.
We give you our honest assessment of the boiler's condition, repair cost, and remaining life so you can decide with full information.
What you can check before calling
A few simple checks can sometimes restore heat or help us diagnose faster. Confirm the thermostat is set to heat and has fresh batteries. Check that the boiler's emergency switch, usually at the top of the basement stairs, is on and that the breaker hasn't tripped. Look at the pressure gauge on hot-water boilers; very low pressure can shut the boiler down. If the boiler has locked out, note any error code or flashing light. Beyond those checks, leave the repair to a technician, particularly anything involving gas valves, burners, or venting.
