Furnace Repair in Mississauga
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 Mississauga homes
What we find on a furnace repair call in Mississauga depends almost entirely on when the house was built. A high proportion of Mississauga homes have a mid-efficiency furnace sharing a masonry chimney with the water heater. When the furnace is upgraded to condensing, that shared flue becomes oversized and starts condensing acid on the liner — worth checking before it becomes a repair.
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 Mississauga means for this job
Erin Mills, Meadowvale and Malton are dense 1970s and 1980s subdivisions built to a handful of repeated plans, so once we have seen one mechanical room on a street we usually know what the rest look like. Port Credit, Clarkson and Lorne Park are older and far more varied, with lake-side properties that were renovated in stages rather than built to one spec. For furnace repair, that matters because the work concentrates on the furnace and its venting — and that is exactly what changes between a Clarkson property and a newer build in Lorne Park.
Timing in Mississauga
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. undefined The lakeshore strip runs a few degrees milder and considerably damper than the north end of the city, which shows up as slower drying, more moss on north-facing roof edges and more corrosion on outdoor equipment near the water.
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. Most Mississauga properties have driveway parking and a walk-out or side entrance to the mechanical room, which keeps labour time down. The cost variable here is usually chimney and venting: whether an upgrade forces a new liner or a side-wall termination.
Permits and jurisdiction
Building permits and mechanical inspections are issued by the City of Mississauga; Region of Peel handles water and wastewater, and TSSA covers all gas work. Enbridge is the gas distributor across the city.

FAQ
Furnace Repair questions from Mississauga 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?
Erin Mills, Meadowvale and Malton are dense 1970s and 1980s subdivisions built to a handful of repeated plans, so once we have seen one mechanical room on a street we usually know what the rest look like. Port Credit, Clarkson and Lorne Park are older and far more varied, with lake-side properties that were renovated in stages rather than built to one spec. On a furnace repair visit in Clarkson, Lorne Park, Cooksville or anywhere else in Mississauga, 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. The lakeshore strip runs a few degrees milder and considerably damper than the north end of the city, which shows up as slower drying, more moss on north-facing roof edges and more corrosion on outdoor equipment near the water. We cover Mississauga from Clarkson through Cooksville, and also serve 3 neighbouring municipalities, so scheduling outside a demand spike usually means a same-week window.
