Furnace Repair & Installation in Mississauga
Mississauga winters demand a furnace that works. When yours fails, Megacity HVAC provides 24/7 emergency repair with TSSA-certified technicians, upfront pricing, and 27 years of experience across the GTA.
Trusted Furnace Repair and Installation for Mississauga Homes
Mississauga is one of the largest cities in Canada, and its housing stock reflects decades of growth — from the historic homes of Streetsville and Port Credit to the suburban developments of Meadowvale and Erin Mills, the established neighbourhoods of Cooksville and Lorne Park, and the high-rise communities of City Centre. Each area has its own HVAC profile, and Megacity HVAC has been servicing all of them for over 27 years.
Many Mississauga homes were built during the suburban boom of the 1970s through 1990s. These homes typically have forced-air natural gas furnaces with ductwork running through the basement and walls. The furnaces installed during that era were mid-efficiency units rated at 78 to 80 percent AFUE. Many of these original furnaces have been replaced once, but homeowners in Meadowvale, Erin Mills, and Churchill Meadows still frequently have furnaces that are 15 to 20 years old and operating well below modern efficiency standards.
For furnace repairs, our TSSA-certified technicians carry the most common replacement parts on every service truck. Whether your Mississauga home has a Lennox, Carrier, Goodman, Trane, or any other brand, we diagnose the issue on-site and complete the repair in most cases on the same visit. Typical repairs include ignitor replacement, flame sensor cleaning, blower motor service, and control board replacement — all with upfront pricing before we begin any work.
When replacement makes more financial sense than repair, we help Mississauga homeowners choose the right high-efficiency system. As an Authorized Lennox Dealer, we offer competitive pricing on one of the most trusted names in home heating. Every furnace we install meets or exceeds 96 percent AFUE — meaning at least 96 cents of every gas dollar goes to heating your home rather than escaping up the flue. For a typical Mississauga home, upgrading from an 80 percent to a 96 percent efficient furnace saves $400 to $600 per year on gas bills.
Mississauga homeowners benefit from Enbridge rebate programs, and as a certified Sustain Trusted Partner, we process all paperwork on your behalf. Qualifying high-efficiency furnaces earn rebates of up to $1,000, and we ensure you receive the full amount without delay.

Common Furnace Problems in Mississauga Homes
We see these issues regularly across Streetsville, Port Credit, Meadowvale, Erin Mills, and every other Mississauga neighbourhood.
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.
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.
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.
Strange Noises
Banging, squealing, rattling, or popping from the furnace or ductwork. Often indicates loose components, a failing blower motor, or sheet metal ducts expanding. Mississauga homes with long duct runs can amplify these.
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.
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 to 80 percent AFUE — modern units hit 96 percent or higher.
