Common Boiler Problems We Repair
No heat or insufficient heat, often caused by a failed circulator pump, a stuck zone valve, or a burner ignition problem.
Pressure loss, which can indicate a leak, a faulty pressure relief valve, or an expansion tank issue. See our boiler losing pressure guide.
Leaks from the boiler or piping, and radiator valve leaks.
Noisy operation, including kettling, banging, or gurgling, which can point to limescale buildup or trapped air.
When to Call for Professional Boiler Repair
Call for service if the boiler is not heating, is leaking, is losing pressure repeatedly, or is making unusual noises.
If you smell gas or suspect a carbon monoxide leak from a gas-fired boiler, leave the building, call your gas utility or 911, and do not operate the boiler. Request professional repair after the immediate hazard is cleared.
