Common furnace problems in Mississauga homes

Mississauga’s housing stock is wildly mixed, and so are the furnace issues we see. In Port Credit, Mineola, and Lorne Park, a lot of 1960s bungalows still run original or second-generation gas furnaces with ductwork that was never meant to push today’s higher static pressures. The result? Noisy blowers, cracked heat exchangers, and cold rooms at the far end of the house.

In Streetsville and Cooksville, we get called out to 1980s two-storeys with aging Lennox and KeepRite units that hit the 20-year mark and start throwing ignition faults. Control board failures are common once the flame sensor and hot surface igniter have been replaced a few times and the board itself gives up.

Newer builds around Square One, Erin Mills, and Meadowvale tend to have high-efficiency condensing furnaces. The problems there skew toward blocked condensate drains, pressure switch faults, and inducer motor bearings. Malton and Clarkson homes often sit between, mid-efficiency units pulled past their intended service life.

Whatever’s happening, we diagnose before we recommend. No upselling to a full replacement when a $250 igniter fixes it.

Our Mississauga furnace repair process

Call comes in, we dispatch a licensed gas tech with the van stocked for your furnace brand. On site, we run a full diagnostic: gas pressure check, flame sensor read, inducer and blower amp draw, limit switch, pressure switch, and control board voltages. You get a written quote before anything gets replaced.

If you approve, the diagnostic fee ($89-$149) comes off the repair total. Most common repairs wrap up in the same visit because we stock igniters, flame sensors, pressure switches, gas valves, capacitors, and universal control boards on the truck. Anything unusual, a proprietary board for a specific Tempstar or Comfortmaker model for instance, we order and usually have back the next day.

Every repair carries a 1-month parts and labour warranty. If the same fault comes back, we come back at no charge. More on our full furnace repair service here.

Cost of furnace repair in Mississauga

Furnace repair in Mississauga typically runs $150 to $600 depending on the part and complexity. Here’s what we see most often:

  • Flame sensor cleaning or replacement: $150 to $220
  • Hot surface igniter: $220 to $320
  • Pressure switch: $250 to $380
  • Blower capacitor: $180 to $260
  • Inducer motor: $450 to $750
  • Gas valve: $400 to $650
  • Control board: $450 to $800
  • Thermocouple (older units): $140 to $200

Diagnostic fee is $89 to $149 and waived if you approve the repair. After-hours and holiday calls carry an emergency premium, usually $50 to $100 above daytime rates. If repair quotes push past $1,200 on a furnace over 15 years old, we’ll talk honestly about whether furnace installation makes more sense long-term. No pressure either way.

Emergency furnace repair

Cold snaps in Mississauga can drop overnight temps below -20C, and a dead furnace at 2 AM isn’t something that waits until morning, especially with kids, pets, or pipes that can freeze in an unheated basement. Our emergency line is 1 (877) 707-1615, answered 24/7.

Before you call, try the basics: thermostat set to Heat and at least 3 degrees above room temp, furnace switch on (looks like a light switch near the unit), furnace filter not completely clogged, breaker not tripped. If you smell gas, don’t troubleshoot. Leave the house, call Enbridge’s emergency line at 1-866-763-5427, then call us once you’re safely outside. See Enbridge’s gas safety guidance for more.

FAQ

How much does furnace repair cost in Mississauga?

Most repairs fall between $150 and $600 including parts and labour. Diagnostic fees run $89 to $149 and get applied to the repair cost if you go ahead. Major component replacements like control boards or gas valves can push $800.

Do you offer same-day furnace repair in Mississauga?

Yes. Call before noon and we’ll almost always have a tech at your door the same day, seven days a week. Emergency calls after hours are dispatched within 60 to 90 minutes across most of Mississauga.

My furnace is blowing cold air, what’s wrong?

Usually one of three things: the thermostat is set to Fan On instead of Auto, the flame sensor is dirty and shutting the burners down, or the pressure switch isn’t closing. All three are common on Mississauga furnaces past the 10-year mark. Any of these is a same-visit fix.

Is it worth repairing a 20-year-old furnace?

Depends on the repair. A $200 igniter on a 20-year-old Lennox that otherwise runs clean? Fix it. A $900 control board or cracked heat exchanger on the same unit? Probably time to replace. We’ll give you the numbers both ways and let you decide.

Do you service furnaces in condos around Square One?

Yes, as long as the unit is in-suite and the condo corporation allows third-party HVAC work (most do). High-rise central systems owned by the building itself need to go through property management.

What brands do you service?

Lennox, KeepRite, Goodman, Tempstar, Ruud, Comfortmaker, and most other major North American brands. We carry universal parts plus brand-specific components for the top sellers in the GTA.

Are your technicians licensed?

Every tech on our team holds a valid TSSA gas technician certification (G2 or G1). We carry $5M liability insurance and WSIB coverage. Ask to see credentials on site, we’re happy to show them.
