Boiler Repair FAQs

Is a broken boiler an emergency repair?

A malfunctioning boiler is most certainly an emergency that requires prompt attention. It’s more than just an inconvenience; if left unrepaired, some problems can pose a significant risk to your family’s safety and the safety of your home.

Why is my boiler on but not heating?

This common problem often indicates problems with the thermostat or the pressure within the boiler. The most common reasons this can occur are broken diaphragms, malfunctioning airlocks, or motorized valves that are stuck.

How do I test my boiler for leaks?

If you suspect your boiler is leaking, we recommend turning off the electricity to the boiler. Then, review the pressure gauge; if the arrow is in the red zone, it can indicate water is leaking through the pressure relief valve. If this is the case, ensure the key or lever isn’t stuck in the “open” position. If the key/lever is not stuck, allow the boiler to cool. You should also bleed the radiators. If these steps fail to stop the leak, it is best to schedule an emergency service appointment.
