“Scheduling around our limited weekends at the cottage was effortless. They finished the ductless install ahead of schedule, labeled the breaker, and texted photos of the completed work.”

Fast Diagnostics and Lasting Fixes for Ailing Boilers
Guelph has a mix of heritage homes with original boiler systems and newer builds with high-efficiency installs, and Guelph Furnace Repair 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
Fuel bills climbing while the house never feels warm enough?
Slow pressure loss means a loop leak, a failing expansion tank, or a tired relief valve. We trace it and fix it properly.
Fast No-Heat and Leak Repairs
Cold radiators, a dripping relief valve, or pressure that keeps dropping show up often in older Guelph housing. We diagnose the real fault, igniter, circulator, or expansion tank, and fix it without pushing a full replacement.
Catch Corrosion Before It Costs You
Hydronic systems fail from the inside out. During maintenance we test water quality, inspect vents and flues for corrosion, check for sludge in the loop, and protect the heat exchanger before rust finds a weak spot.
Local Hydronic Specialists You Can Trust
As a family-run HVAC company in Guelph, our licensed and insured technicians service all boiler makes and models, cast-iron or condensing, with transparent pricing and straight talk from the first phone call to the final walkthrough.
FAQ
Boiler Service in Guelph: Common Questions
How much does boiler service cost in Ontario?
Expect three possible numbers: a diagnostic fee, a repair price, or a replacement quote. Most calls end at the first two, and we explain all three first.
How quickly can you fix a boiler with no heat?
Same-day response is the norm for no-heat calls in heating season. Diagnosis takes under an hour, and the fix follows immediately when the part is on the truck.
Should I repair my old boiler or replace it?
Run the numbers against a winter of fuel bills. If the repair costs a fraction of replacement, fix it. If efficiency is already gone, replace it.

What Guelph Homeowners Say
Real feedback from neighbours we've helped stay comfortable year-round.
“Our gas fireplace pilot kept dying every cold night, and the tech traced it to a worn thermocouple, replaced it same visit, and relit everything perfectly.”

“The previous owners renovated and clearly never touched the ducts. Sawdust and debris came out for an hour straight. Fair quote upfront and not a cent more afterward.”
