Furnace Repair in Toronto
No heat? We diagnose and fix gas and electric furnaces the same day.
A furnace that quits in January is not a maintenance item, it is an emergency. Our gas-licensed technicians carry the ignition, control and blower parts that account for most Ontario furnace failures, so the majority of no-heat calls are resolved on the first visit.

Local context
Furnace Repair for Toronto homes
Across Toronto, furnace repair calls follow the local housing stock closely. Older Toronto chimneys were built for coal and oil, then reused for gas without a liner. It is the single most common safety issue we find inside the old city, and it is why we camera-inspect every flue rather than only sweeping it.
We start every furnace call with a full combustion and safety check, not just a fix for the symptom you reported. That means testing the heat exchanger for cracks, verifying gas pressure against the manufacturer's spec, checking flue draft and confirming the limit and pressure switches are operating inside their ranges. A furnace that heats but vents improperly is more dangerous than one that will not start at all.
Once the cause is identified, you get a written price before we touch a part. If a repair does not make financial sense against the age and condition of the unit, we tell you plainly and show you the numbers rather than quietly replacing components on an appliance near the end of its life.
The failures we see cluster by age. Under eight years old, a no-heat call is usually a flame sensor, a pressure switch tripped by a blocked intake, or a condensate drain that has backed up and shut the unit down on a safety. Past twelve years, the same symptom is more often an inducer motor, a control board, or a heat exchanger that has finally opened up. Knowing which band your furnace is in changes what we test first and how much of your time we spend on it.
We also record what the furnace was doing before it stopped. Static pressure, temperature rise across the exchanger, gas manifold pressure and flame current are numbers, and numbers tell you whether the part that failed was the problem or a symptom of something upstream. A furnace that eats igniters is not an igniter problem — it is usually restricted airflow or a cracked exchanger cooking the ignition circuit, and replacing the igniter alone means you call us again in six weeks.
What the housing stock in Toronto means for this job
Inside the old city you are mostly looking at pre-1940 semis and rowhouses with narrow mechanical rooms, converted gravity ductwork and masonry flues that predate gas. The post-war belt through Etobicoke, North York and Scarborough is bungalows and side-splits on their second or third furnace, and the infill and condo-adjacent stock downtown is high-efficiency and direct-vented from the start. For furnace repair, that matters because the work concentrates on the furnace and its venting — and that is exactly what changes between a Danforth property and a newer build in Annex.
Timing in Toronto
No-heat calls concentrate in the first hard cold snap of the season, when equipment that idled through the shoulder months is asked for full output overnight. In Toronto specifically: Downtown sits in the warmest part of the GTA thanks to the lake and the urban heat island, so shoulder-season demand starts later here than it does up north — but the same heat island pushes summer overnight lows up, which is why AC systems in the old city rarely get the night-time recovery they were sized for.
What it costs here
The failed component sets the floor and the age of the unit sets the ceiling. Parts still in production are inexpensive; obsolete boards and inducers for discontinued models are not. Old-city work carries access costs that suburban work does not: permit parking on narrow streets, laneway-only rear access, tight basement stairs that limit equipment size, and third-floor or rooftop terminations that need ladder or lift time.
Permits and jurisdiction
Permits and mechanical inspections for Toronto addresses go through the City of Toronto, gas work is under TSSA province-wide, and electrical connections are inspected by the ESA. We handle the filing rather than leaving it with you.

What affects furnace repair pricing in Toronto
- Which component failed — an igniter is a fraction of the cost of an inducer motor or control board
- Whether the part is stocked on the truck or has to be ordered for an older model
- Age of the furnace and whether parts are still manufactured
- After-hours or emergency scheduling
- Whether the failure damaged secondary components such as the limit switch or blower
FAQ
Furnace Repair questions from Toronto homeowners
How long does a furnace repair take?
Most repairs are completed in 60 to 120 minutes, including diagnosis and a full safety verification cycle. Repairs that need a special-order part for an older unit typically take two visits.
Is it worth repairing a furnace over 15 years old?
It depends on the failed component. A $200 igniter on a 16-year-old furnace that is otherwise sound is worth doing. A cracked heat exchanger or a failed control board on the same unit usually is not. We give you the repair cost, the replacement cost and the expected remaining life so you can decide with real numbers.
Why does my furnace turn on and off every few minutes?
Short cycling is most often a dirty filter restricting airflow, a flame sensor coated in oxide, a blocked flue, or an oversized furnace for the space. The first two are inexpensive fixes. We test all four before recommending anything.
Do you handle emergency no-heat calls?
Yes. No-heat calls are prioritised ahead of routine maintenance, and we run extended hours through the Ontario heating season.
Is my furnace still under warranty?
Most manufacturers cover heat exchangers for 10 to 20 years and other parts for 5 to 10 years, and the coverage usually survives a change of homeowner. We look the model and serial up before quoting so you are not paying for a part the manufacturer owes you.
Does the age of my home change what usually fails on a furnace here?
Inside the old city you are mostly looking at pre-1940 semis and rowhouses with narrow mechanical rooms, converted gravity ductwork and masonry flues that predate gas. The post-war belt through Etobicoke, North York and Scarborough is bungalows and side-splits on their second or third furnace, and the infill and condo-adjacent stock downtown is high-efficiency and direct-vented from the start. On a furnace repair visit in Danforth, Annex, High Park or anywhere else in Toronto, we work from what the house actually is rather than a standard checklist — the furnace and its venting gets assessed on the property, and you get the readings in writing.
When is the worst time to be without heat here, and how fast can you get out?
No-heat calls concentrate in the first hard cold snap of the season, when equipment that idled through the shoulder months is asked for full output overnight. Downtown sits in the warmest part of the GTA thanks to the lake and the urban heat island, so shoulder-season demand starts later here than it does up north — but the same heat island pushes summer overnight lows up, which is why AC systems in the old city rarely get the night-time recovery they were sized for. We cover Toronto from Danforth through High Park, and also serve 3 neighbouring municipalities, so scheduling outside a demand spike usually means a same-week window.
