What makes the best furnace repair company
Ratings alone do not tell the whole story. The best furnace repair company near you should be licensed and insured with TSSA registration for gas work, which keeps your home safe. It should have consistent five star reviews across Google and HomeStars, not just one or two. It should give you transparent, upfront pricing before any work starts, offer same-day and 24/7 emergency service, stock common parts so most repairs finish on the first visit, and stand behind the work with a warranty. A company that charges a heavy premium for after-hours calls is not the best choice when your heat fails at 2 a.m.
Signs your furnace needs repair now
Some furnace issues can wait a day; others should not. Call for service when you notice no heat or a furnace that will not start, air blowing cold from the vents, loud banging, rattling, or squealing, weak airflow and rooms that never warm up, short cycling where the furnace turns on and off constantly, a spike in your gas bill, or a yellow rather than blue burner flame. If you ever smell gas or burning, or your carbon monoxide alarm sounds, leave the home and call for emergency help right away.
Common furnace problems and repair costs
Here are the issues we see most often in Peel Region homes, with typical repair ranges. All figures are Greater Toronto Area estimates, verified July 2026, and vary with the part, the brand, and labour time.
| Symptom | Likely cause | Typical repair cost | Urgency |
|---|---|---|---|
| No heat or will not start | Igniter, flame sensor, or thermostat | $150 to $400 CAD | High |
| Blowing cold air | Flame sensor or overheating | $150 to $450 CAD | High |
| Loud banging or rattling | Loose part, blower, or ignition delay | $200 to $600 CAD | Medium to high |
| Weak airflow or cold rooms | Blower motor, filter, or ductwork | $150 to $900 CAD | Medium |
| Short cycling on and off | Thermostat, flame sensor, or overheating | $150 to $500 CAD | Medium |
| Gas or burning smell | Leave the home and call immediately | Varies | Emergency |
A diagnostic fee of around $100 CAD is common and is credited toward the repair when you proceed. Costs verified July 2026.
What our diagnostic covers
Every furnace repair call starts with a proper diagnosis, not a guess. Our technician checks the thermostat and controls, the igniter and flame sensor, the blower motor and airflow, the gas valve and pressure, the heat exchanger for cracks, and the safety switches. You get a clear explanation of what failed, the flat price to fix it in writing, and the decision stays yours before any work begins. Because our trucks carry the most common furnace parts, most repairs are completed on the same visit.
Repair or replace: how to decide
A repair is usually the right call for a furnace under about 15 years old with a single failed part and a reasonable cost. Replacement makes more sense when the furnace is 15 to 20 years old, repairs are becoming frequent, or the cost of the fix approaches half the price of a new unit. One repair is never worth it: a cracked heat exchanger cannot be safely repaired because it can leak carbon monoxide, so that always means replacement. A new furnace in Mississauga runs about $3,500 to $7,500 CAD installed, and our team can quote a furnace installation right alongside the repair option so you can compare.
