Most Oakville homes were built between 1981 and 2010, and many of their furnaces are now on borrowed time. Call any hour: we diagnose the fault, give you one price, and only start once you agree.
Typical ranges, not quotes, plus HST. We agree your price before the repair starts.
📞 Call (647) 677-003735% of Oakville homes went up between 1981 and 2000 and 20% between 2001 and 2010. A furnace usually lasts 15 to 20 years, so many houses here are on a second furnace or still running an original that is overdue. The age of the house tells us where to start:
| House built | First things we test |
|---|---|
| 1980 or before | Duct leakage and undersized returns, the gas valve, and the venting where an old chimney-vented furnace was replaced |
| 1981 to 2000 | Hot surface igniter, flame sensor and inducer on the second furnace, and its control board if it is 15 or older |
| 2001 to 2010 | Blower motor, capacitor and heat exchanger on an original builder furnace |
| 2011 to 2021 | Condensate trap, drain and pressure switch, and whether the manufacturer warranty still covers the part |

About 19% of Oakville homes were built in 2011 or later. Their furnaces may still have parts coverage from the manufacturer, though some brands extend it only when the warranty was registered. Find the model and serial number on the furnace label before you call, and we will check whether the failed part is still covered.

Detached houses are 59% of Oakville's homes, and in many of them a single furnace heats two floors plus a finished basement. Long run times wear the same parts, so in a larger Oakville house we check these first:

Row houses are 17% of Oakville's homes. Townhouse furnaces often sit in a closet or a corner of the basement next to the water heater, with the vent pipes leaving through a short side or rear wall, where drifting snow can block them in a storm. In a condo townhouse, tell us about visitor parking and the corporation's contractor rules when you book.

Plenty of no-heat calls end at one of these. If none helps, note the flashing light pattern on the control board and tell us when you call.

Leave the house first. Once everyone is outside, call Enbridge Gas at 1-866-763-5427 for a gas smell, or 911 for a carbon monoxide alarm. After the house is declared safe, call us to find the cause. Leave off any furnace that keeps tripping its rollout or limit switch until a technician has checked it.
A furnace over 15 years old with a cracked heat exchanger, a dead control board or its second big repair of the winter is usually better replaced, and we price both. New Midea and Lennox furnaces start at $3,222 installed in Oakville, or $43.99 a month to rent. See furnace installation in Oakville.
