The Honest Conversation

## What Stops GTA Homeowners From Booking a Furnace Repair

Four hesitations we hear on first calls, and the straight answers behind each one.

“The diagnostic fee feels like a trap.”

Some contractors charge $200 CAD to show up and discount nothing off the repair. Our diagnostic starts at $99 CAD and is waived when you authorise the repair on the same visit. The fee covers a full combustion analysis, CO check, and a written fault report you keep regardless.

“You cannot tell if the technician is really licensed.”

Ontario requires TSSA G1 or G2 certification for any gas furnace work. Ours hold both. Certificate numbers appear on every invoice per B149 fuel code. You can verify any number on the TSSA public registry before the technician starts.

“Nobody will publish the price.”

Our four CAD scope bands are published on this page: diagnostic $99 to $149, standard repair $150 to $950, major repair $600 to $1,500, full replacement $3,500 to $8,500. Scope named, not hidden behind adjectives.

“The furnace is 15 years old, is it worth repairing?”

At 15 years with an intact heat exchanger, 5 to 10 more service years. At 20+, the 95% AFUE efficiency gap justifies replacement. Written repair-vs-replace recommendation on every diagnostic, with the numbers.

## Getting to Your Mississauga Furnace Call

Mississauga routing runs off the QEW, Highway 403, and Highway 401, with Hurontario and Erin Mills Parkway as the main north-south connectors. Same-day dispatch covers L5A, L5B, L5M, L5N, and L5W, and the fastest arrival windows are mid-morning and early afternoon before QEW congestion builds.

Cold-snap demand in Peel Region spikes on the same nights as Toronto, so booking early in the day materially improves your odds of a same-day slot in Port Credit, Streetsville, Meadowvale, and Erin Mills.

## Mississauga Homes and Common Furnace Faults

Port Credit and Streetsville hold a lot of 1960s to 1990s housing where 80% AFUE mid-efficiency furnaces are still running past 20 years. Those units bring ignition faults, blower motor wear, and heat exchanger concerns that need a camera inspection and combustion analysis before anyone recommends a repair.

Meadowvale and Erin Mills subdivisions skew newer, with condensing furnaces where condensate blockages, pressure switch faults, and control board failures are the usual causes of a no-heat call. Either way the diagnostic is the same: full inspection, combustion analysis with a CO monitor, and a written report with CAD costs.

Local Feedback

## What Mississauga Customers Say

> “Blower running, no heat. The gas furnace diagnostic found a failed ignition control module and the repair landed inside the published $300 to $650 CAD range.”

H Hassan A. Erin Mills

> “Twenty-two year old furnace in a 1970s home. The camera inspection showed a cracked heat exchanger, they shut it down safely and quoted the replacement the same day.”

N Nicole P. Port Credit

> “Annual tune-up done properly. They showed me the combustion numbers and the CO reading, then left a documented record for the insurance file.”
