Trusted Furnace Repair and Installation for Mississauga Homes

Megacity HVAC has repaired and installed furnaces across Mississauga since 1999 — from the heritage streets of Streetsville and Port Credit to the suburbs of Meadowvale, Erin Mills, and Churchill Meadows. Our TSSA-certified technicians stock the most common parts on every truck, so most repairs are completed on the first visit with upfront pricing before any work starts.

Many Mississauga homes built between the 1970s and 1990s still run mid-efficiency furnaces at 78–80% AFUE. When replacement makes more financial sense than repair, we install as an Authorized Lennox Dealer and carry Carrier, Trane, Rheem, and Daikin — every unit sized with a proper Manual J calculation, with $0-down Enbridge Sustain lease-to-own available.

Diagnostics

Common Furnace Problems in Mississauga Homes

We see these issues across Streetsville, Port Credit, Meadowvale, Erin Mills, and every other Mississauga neighbourhood. Most are solved same-day.

Furnace Not Starting

Faulty ignitor, flame sensor failure, thermostat issues, or tripped safety switch. Common in Mississauga homes where furnaces have been running for 15+ years without component replacement.

$150 – $350

Blowing Cold Air

Dirty air filter, pilot light issues, gas valve malfunction, or cracked heat exchanger. A cracked heat exchanger is a carbon monoxide hazard — call immediately if you notice this symptom.

$100 – $500

Short Cycling

Furnace turns on and off without completing a heating cycle. Usually caused by an oversized unit, clogged filter, thermostat issues, or restricted airflow — common when the wrong-sized furnace was installed.

$100 – $400

Strange Noises

Banging, squealing, rattling, or popping from the furnace or ductwork. Often a failing blower motor, loose hardware, or sheet metal ducts expanding. Long duct runs in Mississauga homes can amplify these sounds.

$150 – $450

Yellow Burner Flame

A yellow or flickering flame instead of steady blue indicates incomplete combustion and potential carbon monoxide production. This is a safety emergency requiring immediate professional inspection.

$150 – $300

Rising Gas Bills

If your Enbridge bill keeps climbing despite normal usage, your furnace is losing efficiency. Many Mississauga homes from the 1980s still run mid-efficiency furnaces at 78–80% AFUE — modern units reach 96–97%.

Common Questions

Furnace Repair Mississauga — FAQ

How much does furnace repair cost in Mississauga?

Furnace repair in Mississauga typically costs between $150 and $500 depending on the issue. Simple repairs like ignitor replacement, flame sensor cleaning, or pressure switch replacement run $150 to $300. More involved repairs including blower motor replacement, control board repair, or inducer motor replacement cost $300 to $500. We always diagnose the issue and provide upfront pricing before beginning any work.

Do you offer 24/7 emergency furnace repair in Mississauga?

Yes. We provide around-the-clock emergency furnace repair across all of Mississauga, including Streetsville, Port Credit, Meadowvale, Erin Mills, Cooksville, Lorne Park, Clarkson, and Mississauga City Centre. A furnace failure in a Mississauga winter can lead to frozen pipes within hours. Call (416) 286-5665 at any time and we dispatch a TSSA-certified technician.

Should I repair or replace my Mississauga furnace?

Consider replacement if your furnace is over 15 years old, needs frequent repairs (more than once per season), has a cracked heat exchanger, or the repair cost exceeds half the price of a new unit. Many Mississauga homes built in the 1980s and 1990s still have mid-efficiency furnaces running at 78 to 80 percent AFUE. A new 96 percent AFUE furnace costs $3,500 to $6,500 installed and can cut gas bills by 20 to 30 percent.

What furnace brands do you install in Mississauga?

As an Authorized Lennox Dealer, we recommend Lennox for premium performance and warranty coverage. We also install Carrier, Trane, Ducane, Rheem, and Daikin. Every furnace we install in Mississauga meets or exceeds 96 percent AFUE efficiency. We help you choose the right brand and model based on your home size, budget, and heating requirements.

What financing options are available for a new furnace in Mississauga?

Standard furnaces are no longer eligible for government rebates. The Enbridge Sustain lease-to-own program lets Mississauga homeowners get a new furnace with $0 down — installation, maintenance, and all repairs included in one monthly payment. Heat pumps may qualify for rebates under the Home Renovation Savings program. We walk you through the options that apply to your situation.
