BOILER Repair in AURORA

A boiler that won’t start is usually caused by a failed thermostat, a tripped circuit breaker, low pressure, or a malfunctioning ignition system. Sometimes the safety lockout feature activates when the system detects an internal issue. A professional inspection can identify the root cause and get your boiler running safely again.

If your boiler isn’t producing hot water, the problem may stem from a broken diverter valve, low pressure, a faulty thermostat, or mineral buildup inside the system. These issues restrict heat transfer and prevent the water from reaching the right temperature.

Different sounds indicate different issues:

Kettling (a rumbling noise) often means sediment buildup is restricting water flow and causing the boiler to overheat.

Whistling or screeching may point to trapped air or a failing pump.

Banging can signal delayed ignition, loose components, or pressure problems.

Boilers are designed to operate quietly — unusual noises are always a warning that internal parts are wearing out or something is overheating.
