Furnace Repair & Installation in Toronto

When your furnace stops working in a Toronto winter, you need a team that answers the phone and shows up fast. At Megacity Heating & Air Conditioning, we have been providing furnace repair and installation services across Toronto and the Greater Toronto Area since 1999. Our TSSA-certified technicians respond to emergency calls around the clock — day or night, weekdays or holidays — because a furnace failure in January is never something that can wait until Monday.

Toronto's housing stock is incredibly diverse, from century homes in the Annex and Cabbagetown to post-war semis in East York and modern builds in Liberty Village. Each home type presents unique furnace challenges. Older homes may have undersized or deteriorating ductwork that affects furnace performance. Larger homes with multiple floors often struggle with uneven heating. Our technicians have worked on every type of Toronto home and furnace configuration for over 27 years.

For repairs, we stock the most common replacement parts on every service truck — ignitors, flame sensors, pressure switches, blower motors, and control boards for all major brands. This allows us to complete most furnace repairs in a single visit, typically within one to two hours. Repair costs range from $150 to $500 depending on the issue, and we always provide an upfront diagnosis and price before starting any work.

When your furnace is beyond economical repair — typically when it is over 15 years old, has a cracked heat exchanger, or needs repairs costing more than half the price of a new unit — we help Toronto homeowners transition to a modern high-efficiency system. A new 96% AFUE gas furnace costs between $3,500 and $6,500 depending on the model and your home's requirements. As a certified Enbridge Sustain Trusted Partner, we process rebate applications on your behalf, potentially saving you up to $1,000 on qualifying equipment.

Our installation process includes a thorough home assessment, proper load calculation, professional removal and disposal of your old furnace, expert installation of the new system, complete safety testing, and thermostat calibration. We walk you through your new furnace operation and leave your home clean. Every installation includes a manufacturer warranty and our own workmanship guarantee.
