Boiler Repair in Toronto & the GTA
Hot water boilers, radiators, in-floor heating — repaired by licensed technicians. 24/7 emergency service.
Many older homes in Ontario — especially in Toronto, Barrie, and the surrounding communities — rely on hot water boiler systems for heating. These systems use a boiler to heat water, which then circulates through radiators, baseboard heaters, or in-floor radiant loops to warm your home.
Boiler systems are durable and efficient when properly maintained, but they do require specialized knowledge to repair. Our licensed technicians understand hydronic heating systems inside and out — from the boiler itself to every radiator, circulator pump, zone valve, and expansion tank in the system.
We provide 24/7 emergency boiler repair across the GTA to Barrie. If your boiler has stopped working, is leaking, or is not heating properly, call us at (647) 491-6009 and we will get a technician to you.
Common Boiler Problems We Fix
No Hot Water or Heat
Boiler not producing hot water or not heating your radiators — could be a faulty circulator pump, thermostat, or gas valve.
Uneven Heating
Some radiators hot while others stay cold usually means air trapped in the system or a failing zone valve.
Leaking Boiler
Water dripping from the boiler, pipes, or pressure relief valve. Leaks worsen fast and need immediate attention.
Pressure Problems
Boiler pressure too high or too low. Both cause performance issues and can trigger safety lockouts.
Pilot Light Issues
Pilot light going out repeatedly or burning yellow instead of blue — a sign of combustion or thermocouple problems.
Strange Noises
Kettling, banging, gurgling, or whistling from your boiler usually indicates scale buildup or trapped air.
