You should have your furnace professionally serviced once a year, ideally in early autumn before cold Ontario winter weather sets in. Annual tune-ups ensure optimal fuel efficiency, reduce unexpected winter breakdown risks, maintain active manufacturer warranties, and verify safe operation against carbon monoxide leaks.

Key indicators requiring rapid professional attention include:

• Cold air blowing from your heat vents.
• Loud banging, rattling, or squealing noises.
• Frequent short-cycling (turning on and off rapidly).
• Unusual burning, gas, or metallic smells.
• A burner flame that glows yellow/orange instead of sharp blue.

With annual preventative maintenance, a modern gas furnace in the Greater Toronto Area typically lasts 15 to 20 years. Systems operating without regular filter changes or annual tune-ups often suffer early major component failure within 10 to 12 years.

If your furnace is over 15 years old and a single repair quote exceeds 50% of the cost of a brand new furnace unit, replacement is usually the smarter long-term investment. Modern high-efficiency models yield lower monthly energy bills to help recover installation costs.

In Toronto and the GTA, a full high-efficiency furnace replacement generally costs between $3,500 and $7,500+ CAD depending on BTU capacity requirements, AFUE efficiency rating, motor speed type (single, two-stage, or variable ECM), and ductwork modifications.

Common culprits include a thermostat set to 'ON' instead of 'AUTO', a clogged air filter causing safety high-limit shutoffs, a dirty flame sensor, or a tripped breaker. Check your air filter first—if replacing it doesn't solve it, call for certified diagnostic repair.
