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 dangerous carbon monoxide leaks.
Key indicators that require professional technician intervention include:
With annual preventative maintenance, a modern gas furnace in the Greater Toronto Area typically lasts 15 to 20 years. Systems that lack regular tune-ups or operate with dirty, restricted air filters often experience major component failures within 10 to 12 years.
A good rule of thumb: If your furnace is over 15 years old and a single repair cost exceeds 50% of a new furnace unit price, replacement is usually the smarter long-term investment. Modern units significantly lower monthly gas bills while providing far more consistent heating comfort.
In Toronto and the surrounding GTA, complete furnace replacement and installation costs typically range between $3,500 and $7,500+ CAD depending on BTU size, efficiency ratings, and venting modifications.
Most GTA homes require 30 to 60 BTUs per square foot. Our licensed technicians conduct precise Manual J load calculations to size your equipment accurately without under- or over-sizing.
Common triggers include an incorrect thermostat fan setting, a clogged filter causing overheating, a blown limit switch, or a tripped circuit breaker.
