Common Boiler Emergencies We Fix Daily

Boilers rarely break down at a convenient time. If your system is experiencing any of the following critical issues, shut off your gas supply if you suspect a leak, and call us immediately:

Symptoms	Likely Cause	What We Do
No Heating or Hot Water	Failed pump, faulty motorized valve, or broken diaphragm.	Diagnose the mechanical failure and replace the component on-site.
Boiler Leaking Water	Compromised internal seals, high pressure, or a fractured valve.	Isolate the leak, test system pressure, and seal or replace parts.
Clunking or Banging Noises	"Kettling" caused by sludge buildup or a failing heat exchanger.	Clear blockages, check the pump status, and restore quiet operation.
Error Codes / Dropping Pressure	Persistent pressure drops usually indicate a system leak or expansion vessel fault.	Repressurize the system, find the hidden pressure leak, and reset the lockout code.
