Furnace Repair Concerns We Hear on Every First Call
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.

Scarborough Dispatch and Response
Scarborough routing runs off Highway 401, Kingston Road, Lawrence, and McCowan, giving same-day coverage from Cliffside through Agincourt and Malvern.
Winter storm days along the Bluffs slow surface routes. We keep the 4-hour cold-snap target by triaging no-heat calls ahead of routine maintenance visits.
Scarborough Housing Stock and Furnace Age
Agincourt, Guildwood, and Cliffside are dominated by 1950s to 1980s detached and semi-detached homes. Furnaces there are frequently past 18 years, so ignition faults, blower motor failure, and heat exchanger inspection make up most of the work.
Malvern and newer pockets run more recent equipment where condensate, pressure switch, and control board faults dominate. Both get the same diagnostic: full inspection, combustion analysis with a CO monitor, and a written report with CAD costs.
What Scarborough Customers Say
“Furnace was banging on startup. They found a delayed ignition problem, cleaned and replaced the right parts, and showed me the combustion readings afterwards.”
“No heat on a Saturday night. After-hours diagnostic quoted upfront, blower motor replaced, and the fee came off the bill when I approved the work.”
“Old furnace, real answers. They confirmed the heat exchanger was intact and told me it was fine to keep running another few seasons.”
