“Furnace refused to ignite on the first really cold morning. They diagnosed the failed igniter from my description, arrived with the part on hand, and we were warm by lunch.”

Boiler Repair, Installation & Maintenance in Guelph
Guelph has a mix of heritage homes with original boiler systems and newer builds with high-efficiency installs, and Guelph HVAC Pros services them all. We repair and replace cast-iron gas boilers in older homes and condensing modulating units in newer ones, radiator or in-floor.
Why Homeowners Call Us
Radiators cold upstairs while the boiler runs non-stop?
Slow pressure loss means a loop leak, a failing expansion tank, or a tired relief valve. We trace it and fix it properly.
Leaking Boilers Handled Before Damage Spreads
A slow weep from a seal or valve can wreck flooring and basements finished around the boiler. We isolate the leak, repair what is repairable, and give you a straight answer if the section itself is cracked.
Fall Start-Ups That Prevent Winter Calls
The best time to find a boiler problem is October, not January. Book a fall start-up and we will bleed radiators, test the aquastat, inspect the circulator, and leave you a system ready for a hard Ontario winter.
Technicians Who Know Hydronic Heating
Boilers are a trade of their own, and not every HVAC tech is fluent in them. Ours bleed, balance, and troubleshoot hydronic systems week in and week out, on gas, propane, and oil burners alike.
FAQ
Boiler Service in Guelph: Common Questions
How much does boiler service cost in Ontario?
It depends on the fault. A failed igniter or relief valve is a modest repair, a leaking heat exchanger is not. We diagnose, then quote, and the quote is free.
How quickly can you fix a boiler with no heat?
During cold snaps we triage, households with no heat at all go first. Typical timeline from call to warm house is same day to next morning.
Should I repair my old boiler or replace it?
We repair willingly when the heat exchanger is sound and parts exist. Replacement earns our recommendation when the cast iron cracks or parts go obsolete.

What Guelph Homeowners Say
Real feedback from neighbours we've helped stay comfortable year-round.
“Booked a service because the pilot flame looked weak and orange. He tuned the burner, adjusted the pilot, and now the glass stays clean and the heat is noticeable.”

“My garage finally stays warm enough for winter projects. The crew mounted the mini-split neatly, hid the line set behind the wall, and cleaned up completely.”
