Four reasons, any one of them enough to make the visit worth booking.
Keeps warranty coverage valid
Most major brands require documented annual professional maintenance to honour their 10-year parts warranty. Skipping years can void coverage on the most expensive components.
Catches safety issues early
The heat exchanger inspection and combustion analysis are the checks that matter most. A cracked heat exchanger leaks carbon monoxide into the home. Annual inspection catches it before it becomes a hazard.
Protects efficiency, lowers gas bills
A neglected furnace can lose 5-10% efficiency. On a typical Ontario heating bill of $1,800-$3,500 per season, that lost efficiency roughly equals the cost of the visit itself.
Extends equipment life
A well-maintained furnace typically lasts 15-20 years. A neglected one often fails between years 10 and 13. Usually from a small problem that grew into a major failure.
Common questions
How often should an Ontario furnace be serviced?
Once a year, ideally in September or October before heating season starts. Most major manufacturers (Lennox, Carrier, Goodman, Trane) require documented annual professional maintenance to keep their 10-year parts warranty valid. Skipping years can void coverage on the most expensive components like the heat exchanger and inducer motor.
What's the difference between a furnace tune-up and furnace maintenance?
Practically, none. The terms are interchangeable in residential HVAC. A tune-up (or maintenance visit) typically includes a 12-point inspection covering combustion analysis, gas pressure verification, flame sensor cleaning, burner inspection, heat exchanger visual inspection, blower motor amp draw, pressure switch test, filter replacement, and a written photo report. Pricing is $149 flat for a single visit through EcoFrost.
Will an annual furnace tune-up actually save money?
Modestly but consistently. A well-maintained 96%+ AFUE furnace runs at its rated efficiency. A neglected one (dirty burners, blocked secondary heat exchanger, undersized airflow from clogged filters) can lose 5-10% efficiency over time. On a typical Ontario gas bill of $1,800-$3,500 per heating season, that's roughly $90-$350 per year. The tune-up usually pays for itself across one or two winters.
Does EcoFrost service all furnace brands across the GTA?
Yes. We service Lennox, Carrier, Goodman, Trane, York, Bryant, Daikin, Napoleon, Rheem, Heil, Comfortmaker, ICP, and other major residential furnace brands. We are an authorized Lennox dealer with TSSA-licensed gas technicians. The $149 maintenance price applies regardless of who originally installed the unit.
Are there extra charges for evenings or weekends?
No. EcoFrost charges the same $149 flat rate for furnace maintenance visits regardless of time of day or day of week. No overtime fees, no holiday surcharge. Response time during evenings and weekends may be slightly longer during peak heating season demand.
What if the maintenance visit finds something wrong with my furnace?
You receive a written photo report showing exactly what we found, with a flat-rate quote for any recommended repair. You decide whether to proceed immediately, schedule later, or hold off. The $149 maintenance fee is not contingent on you agreeing to any repair. For furnaces near end of life (15+ years old), we run the replace-vs-repair math during the visit and discuss current rebate options.
