The Honest Answers to Common Furnace Repair Hesitations
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.

How We Dispatch Across Vaughan and York Region
Vaughan routing runs off Highway 400, Highway 407, Highway 7, and Major Mackenzie, which makes Concord and Maple quick to reach outside peak hours and makes Kleinburg the longest run in the city. On a cold-snap no-heat call we target a 4-hour window across L4H, L4J, L4K, and L4L.
Suburban driveways make access simple, so most Vaughan visits start on time. The variable is the weather itself: the first hard freeze of the season produces a call spike across York Region, and the earlier in the day you book, the more likely a same-day slot is still open.
Vans carry the parts that fail most often in Vaughan homes: hot surface ignitors, flame sensors, pressure switches, ECM and PSC blower motor capacitors, and circulator pump spares for the Woodbridge boiler stock. Standard repairs finish in 60 to 120 minutes on the first visit wherever the part is on the van.
Vaughan Housing Stock and How It Fails
Maple, Concord, and Vellore Village subdivisions built from the late 1990s onward run mid and high-efficiency gas furnaces with ECM blowers. Their most common faults are ignition components, pressure switch and condensate blockages on condensing units, and control board failures, not whole-system replacement.
Older Woodbridge homes are a different profile. Cast-iron sectional and condensing combi boilers with hydronic radiant heat are common, and the failures cluster around circulator pumps, expansion tanks, pressure relief valves at 30 PSI, and aquastat controls. We service and balance those systems rather than pushing a forced-air conversion that the house was not built for.
Larger Kleinburg and Vellore homes often have two-stage or zoned systems where a comfort complaint turns out to be a staging or thermostat wiring issue rather than a failed furnace. We verify staging and C-wire configuration before recommending any hardware.
What Vaughan Customers Say
“Our boiler dropped pressure twice in a week. The boiler repair visit found a failed expansion tank, replaced it the same afternoon, and rebalanced the radiant loops so the upstairs finally holds temperature.”
“Furnace was short-cycling every few minutes. Turned out to be a blocked condensate line and a tired pressure switch. Quoted before the work started, finished inside two hours.”
“Booked a high-efficiency furnace conversion after the emergency call. They walked through the 95% AFUE numbers, handled the venting upgrade, and filed the Enbridge rebate paperwork for us.”
