All specifications are published by the manufacturer. We install and service these systems across Toronto & the GTA.
Tell us the symptoms over the phone. We dispatch a tech with the right parts for North York furnace calls.
Ignitor, flame sensor, heat exchanger, blower, gas valve, and control board — we check every component.
A clear explanation and a fixed repair price. You approve before any work starts. No surprises on the invoice.
We fix it, run a full heating cycle, verify temperature rise through the ducts, and clean up before leaving.
Most are diagnosed and repaired in a single visit with parts we carry on our trucks.
Thermostat misconfiguration, failed ignitor, faulty gas valve, or a tripped safety switch. Common in North York homes through the winter months — we diagnose and resolve within one visit.
Your furnace starts and stops without completing a full heating cycle. Usually a dirty filter, failing flame sensor, or thermostat placement issue. Common in older North York bungalows.
Rattling, banging, or high-pitched whining from the furnace — typically a loose blower wheel, worn bearings, or expanding ductwork. Ignoring these leads to more expensive repairs.
A cracked heat exchanger or improper venting can produce CO. If your detector alarms or you notice a yellow burner flame, shut the furnace off immediately and call us.
Some rooms warm, others cold — common in multi-level North York homes. Often caused by undersized ductwork, a failing blower motor, or a damper stuck in the wrong position.
If your Enbridge bill climbs without more usage, the furnace is losing efficiency. A tune-up catches it early; a 96% AFUE replacement cuts heating costs significantly.
Authorized Lennox Dealer — and fully equipped to install, repair, and maintain every major HVAC brand sold in Ontario.












Standard gas furnaces are not covered by current rebate programs — but as a certified Enbridge Sustain Trusted Partner, we install a new high-efficiency furnace with nothing down. One predictable monthly payment covers installation, annual maintenance, and repairs.
Our technicians are dispatched from East York and typically reach North York homes within 60 to 90 minutes for emergency calls. We serve all North York neighbourhoods including Don Mills, Willowdale, Bayview Village, and Lawrence Park. For non-emergency repairs, we offer same-day and next-day appointments with a two-hour arrival window so you are not waiting around all day.
Furnace repair costs in North York range from $150 to $500 for most common issues. Simple fixes like flame sensor cleaning or thermocouple replacement are on the lower end. Blower motor replacements or control board repairs are on the higher end. We always provide upfront pricing before starting work. For a new furnace installation, expect $3,500 to $6,500 depending on the efficiency rating and home size.
We recommend a minimum 96% AFUE rating for North York homes. This means 96 cents of every dollar spent on gas goes directly to heating your home, compared to 60-70% efficiency in furnaces over 20 years old. The energy savings typically pay for the upgrade within 3 to 5 years. The Enbridge Sustain lease-to-own program also lets North York homeowners get a new furnace with $0 down — maintenance and repairs included.
Yes. Our TSSA-certified technicians service every major furnace brand including Lennox, Carrier, Trane, Ducane, Rheem, Daikin, York, and more. As an Authorized Lennox Dealer, we offer competitive pricing on new Lennox and Ducane installations. For repairs, we stock common parts for all brands on our trucks to complete most jobs in a single visit.
Tell us what your furnace is doing and we will get back to you fast. Same-day service available across North York and the GTA — or call and talk to a real person now.
Proudly serving Toronto & the Greater Toronto Area from our East York office since 1999.
