That is the whole standard we hold ourselves to. ### 20+ Years of Furnace Repair Experience Two decades of TSSA-licensed gas furnace repair, high-efficiency conversions, boiler service, and emergency dispatch across Toronto and the GTA. Furnace work is the whole business, not a sideline to plumbing or general contracting. That focus is why a technician can name the fault on the first visit instead of swapping parts until the heat comes back. ### Same-Day GTA Emergency Dispatch Toronto, Vaughan, Mississauga, Brampton, Markham, Richmond Hill, North York, Scarborough, Etobicoke, and Thornhill. Cold-snap no-heat calls are prioritised within 4 hours, and the diagnostic fee is quoted in CAD before the van leaves. Booking early in the day gives the best chance of a same-afternoon slot during a freeze. ### Transparent CAD Pricing Published Diagnostic $99 to $149, standard repair $150 to $950, major repair $600 to $1,500, full 95% AFUE replacement $5,500 to $8,500. The diagnostic fee is waived when you authorise the repair on the same visit, and every quote itemises diagnostic, parts, labour, and disposal separately. ### TSSA G1/G2 Licensed Technicians Only No apprentices sent alone. Every repair meets Ontario B149 fuel code, and certificate numbers appear on every invoice so you can verify them on the TSSA public registry before work starts. Combustion analysis and a CO reading are part of every visit, not an upsell. ### High-Efficiency Rebate Coordination ENERGY STAR installer for Enbridge Home Efficiency Rebate Plus (up to $6,500 CAD) and the Canada Greener Homes Grant (up to $5,000 CAD). We file the rebate paperwork for you, which is the step most homeowners lose money on when they handle a conversion themselves. ### No-Surprise Warranty and Parts Manufacturer certified for Lennox, Carrier, Trane, Goodman, Napoleon, York, Rheem, and Bryant. We fit Ontario distributor parts so your manufacturer warranty stays valid, and the parts and labour warranty is issued in writing at the end of the job. The Honest Conversation ## What Actually Stops Toronto Homeowners From Calling a Furnace Technician 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. From Call to Verified Repair ## How Our Toronto Furnace Diagnostic Process Works, 5 Steps Every furnace call follows the same documented process, from booking through post-repair combustion verification. 01 ### Booking and Dispatch Send your postal code, furnace age (or year installed), and symptom. Same-day or next-morning slot booked. Diagnostic fee quoted upfront in CAD. 02 ### On-Site Inspection Full furnace assessment: heat exchanger, ignition system, blower motor, flame sensor, gas valve, combustion analysis with CO monitor, flue draft, and thermostat response. 03 ### Written Diagnostic with Options You receive a written report with the fault identified, parts required, CAD labour and parts cost, and either a repair or replacement recommendation based on furnace age, efficiency, and cost. 04 ### Repair or Replacement Scheduled Repair authorised same-visit gets the diagnostic fee waived. Replacement scheduled within 3 to 5 business days, or 24 hours for an emergency no-heat situation. 05 ### Post-Service Verification and Warranty Combustion analysis re-run, CO reading verified, thermostat cycle tested, and the parts and labour warranty issued in writing, typically 1 to 5 years depending on the part and manufacturer. ![Written furnace diagnostic report with CAD pricing beside a digital manometer and multimeter](/images/maps/close-up-of-a-written-furnace-diagnostic-report-wi.webp) Published CAD Scope Bands ## What a Toronto Furnace Call Actually Costs Furnace repair is not a packaged product.

A technician who only knows one of those profiles will guess on the other two. Over 20+ years we have worked all of them across the GTA, which is why the diagnostic starts with combustion analysis and a CO reading rather than a parts catalogue. The most expensive mistake in this trade is replacing a component that was never the cause. A furnace that short-cycles every three minutes might have a dirty flame sensor, a failing pressure switch, a blocked condensate trap, or a unit that was oversized when it was installed. Each has a different fix and a different CAD cost. The written diagnostic names which one it is, backed by the readings, before you approve anything. The second most expensive mistake is repairing a furnace that should be replaced. Gas furnaces last 15 to 25 years. Past 20 years, with a cracked heat exchanger or repeat failures, the efficiency gap between an old 80% AFUE unit and a modern 95% AFUE unit pays back in 6 to 10 years, before Enbridge Home Efficiency Rebate Plus and Canada Greener Homes Grant offsets. That is why every diagnostic carries a written repair-vs-replace recommendation with the numbers behind it.

Furnace repair costs $150 to $950 CAD for standard repairs (thermocouple, capacitor, blower motor, ignition control). Major repairs including heat exchanger work run $600 to $1,500 CAD. Full replacement is $3,500 to $8,500 CAD. Diagnostic starts at $99 CAD, waived on same-visit repair. ### What is the diagnostic fee for a furnace repair call? $99 to $149 CAD business hours, $199 to $299 CAD after hours. Fully waived when you authorise repair on the same visit. ### How long does emergency furnace repair take? Same-day dispatch for cold-snap calls. Most standard repairs complete in 60 to 120 minutes. Heat exchanger work takes 3 to 5 hours. ### Do I need a TSSA-licensed technician for furnace work in Ontario? Yes. Ontario B149 fuel code requires TSSA G1 or G2 certification for any natural gas or propane furnace work. Our technician certificate numbers appear on every invoice. ### How old should a furnace be before I replace it? Gas furnaces last 15 to 25 years. Repair if under 15 with an intact heat exchanger. Replace at 20+ where the 95% AFUE efficiency gap pays back in 6 to 10 years. ### What Ontario rebates apply to a high-efficiency furnace? Enbridge Home Efficiency Rebate Plus up to $6,500 CAD (qualifying 95% AFUE with insulation upgrade). Canada Greener Homes Grant up to $5,000 CAD. We file the rebate paperwork on your behalf. ### 80% AFUE vs 95% AFUE, what is the difference? 80% AFUE mid-efficiency: $3,500 to $5,500 CAD installed. 95% AFUE high-efficiency: $5,500 to $8,500 CAD installed but cuts natural gas bills 15 to 20 percent and qualifies for Ontario rebates. ### How often should a Toronto furnace be tuned up? Once per year before the first cold snap. Most Ontario home insurance policies require annual tune-up records for warranty coverage. Our 12-point tune-up is $149 to $249 CAD. ### Can you repair a rental furnace from Reliance, Enercare, or Simply Green? Yes. We service any rental furnace and give honest advice on buying it out or replacing with a purchased unit. ### What areas do you serve around Toronto? Toronto core, Vaughan (Woodbridge, Concord, Maple, Thornhill), Mississauga, Brampton, Markham, Richmond Hill, North York, Scarborough, and Etobicoke. Same-day GTA dispatch. ### How do I know if my furnace has a cracked heat exchanger? Burning smell, soot near vents, unusual CO alarm activation, yellow or flickering flame, or elevated CO on combustion analysis. A cracked heat exchanger requires immediate replacement ($600 to $1,500 CAD) or full furnace replacement if the unit is 15+ years old. ### Can a cold-climate heat pump replace my gas furnace? Yes. Ontario-rated cold-climate heat pumps operate down to minus 25 Celsius, save 30 to 50 percent on winter energy costs, and qualify for Enbridge and federal rebates. Installation $6,500 to $14,500 CAD. ### Still have a question about your furnace? Tell us the symptom, the furnace age, and your postal code.
