Trusted Furnace Experts for North York Homes
North York is one of the most diverse residential areas in the GTA, with housing stock ranging from mid-century bungalows in Don Mills to newer condos along Yonge Street and large custom homes in Bayview Village. Each home type presents different furnace challenges, and our technicians have worked on them all. At Megacity Heating & Air Conditioning, we have been providing furnace repair and installation services to North York homeowners for over 27 years.
A furnace breakdown in the middle of a North York winter is more than an inconvenience — it is a safety concern. Temperatures in North York regularly drop below minus 15 degrees Celsius in January and February, and a failed furnace can mean frozen pipes and serious property damage within hours. That is why we offer true 24/7 emergency furnace repair with technicians ready to respond day or night, including weekends and holidays.
For same-day non-emergency repairs, we provide a two-hour arrival window and stock common parts like ignitors, flame sensors, blower motors, and control boards on every service truck. Most repairs are diagnosed and completed in a single visit, typically within one to two hours. We charge between $150 and $500 for most furnace repairs, and we always quote the price before starting so there are no surprises on your invoice.
When repair is no longer the smart option — typically when your furnace is over 15 years old, needs frequent service, or has a cracked heat exchanger — we help North York homeowners transition to a new high-efficiency system. A modern 96% AFUE gas furnace costs between $3,500 and $6,500 installed. As a certified Enbridge Sustain Trusted Partner, we process rebate applications on your behalf, potentially saving you up to $1,000 on qualifying equipment.
Quick Facts
Common Furnace Issues We Fix in North York
No Heat Output
Thermostat misconfiguration, failed ignitor, faulty gas valve, or tripped safety switch. We systematically diagnose and resolve the issue, often within an hour.
Frequent Cycling
Your furnace starts and stops repeatedly due to a dirty filter, failing flame sensor, or thermostat placement issues. Common in older North York homes with original thermostats.
Unusual Noises
Rattling, banging, or high-pitched whining from your furnace. Usually indicates a loose blower wheel, worn bearings, or expanding ductwork. Ignoring these leads to costlier repairs.
Carbon Monoxide Risk
A cracked heat exchanger or improper venting can produce carbon monoxide. If your CO detector alarms or you notice a yellow furnace flame, shut off your furnace and call us immediately.
Uneven Heating
Some rooms warm while others stay cold. Can be caused by undersized ductwork, a failing blower motor, or damper issues. Particularly common in multi-level North York homes.
High Gas Bills
If your Enbridge bill jumps without increased usage, your furnace may be losing efficiency. A tune-up or upgrade to a 96% AFUE unit can cut your heating costs significantly.
