What is included in our $149 furnace tune-up
A real tune-up is not a 10-minute visual check. Our techs spend 60 to 90 minutes on a typical residential furnace and run through 21 specific tests and adjustments. Here is the full list.
Why an annual furnace tune-up pays for itself
Warranty protection
Most manufacturers require documented annual maintenance to keep extended warranty coverage active. Skipping years can void $2,000+ in heat exchanger or inducer motor coverage.
Energy savings
Tuned furnaces run 5 to 12 percent more efficiently. For a typical Mississauga home, that translates to $80 to $180 per year in gas savings, more than covering the tune-up cost.
Safety
Combustion analysis catches cracked heat exchangers, blocked vents, and CO leaks before they harm anyone. This is the single most important reason to tune up an older furnace.
When to book your tune-up
September through early November is ideal. Booking before the first cold snap means short wait times (under a week typically) and avoids the November-December crush when emergency calls dominate every contractor's schedule.
Spring tune-ups in April and May work too, especially if you skipped fall. Spring service catches issues that built up over a hard winter and gives parts time to ship before the next heating season. Many homeowners pair a spring AC tune-up with a furnace check during the same visit.
The worst time to book is January and February. Wait times stretch to two and three weeks, premium pricing applies, and most contractors prioritize active no-heat emergencies over scheduled maintenance. If your furnace runs without issue, plan ahead for September.
Red flags to watch when shopping for a tune-up
- $59 to $79 specials with vague descriptions. These are almost always loss-leaders set up to upsell repairs once the tech is in your home. A real tune-up costs more than $80 to deliver honestly.
- No combustion analysis listed. A tune-up without combustion testing skips the single most important safety check on a gas furnace.
- No written report. If the tech leaves without paperwork showing what was tested and what the readings were, you have no record for warranty claims.
- Commission-based techs. Some contractors pay techs a percentage of parts they sell on tune-up visits. EcoFrost techs are salaried with no commission, so recommendations are objective.
- High-pressure replacement pitch. A reputable tech reports what they find with photos and gives you time to think. Walk away from anyone pushing a same-day $8,000 furnace replacement after a tune-up.

Frequently Asked Questions
Got questions about HVAC services in the GTA? We've got answers.
A standard residential furnace tune-up in Ontario costs $129 to $249 depending on the contractor, region, and what is included. EcoFrost charges a flat $149 across the GTA, which includes a full 21-point inspection, combustion analysis, safety check, and a written report. Basic visual-only checks from $79 contractors typically skip combustion testing and safety calibration. Premium service plans that include emergency credits run $249 to $399 annually.
Our flat $149 furnace tune-up includes: full combustion analysis with a calibrated analyzer, blower amp draw test, gas pressure check, heat exchanger inspection with mirror and scope, thermostat calibration, flame sensor cleaning, burner cleaning, condensate drain inspection, vent and intake check, carbon monoxide test, blower wheel and filter check, capacitor and ignitor test, gas valve verification, safety switch test, and a written report with photos of any concerns.
Every year, ideally in September or October before heating season starts. Most manufacturer warranties (Lennox, Carrier, Goodman, Trane) require annual professional service to remain valid. Skipping years voids warranty coverage on major parts like the heat exchanger and inducer motor. We also recommend tune-ups for furnaces older than 15 years, because catching small issues prevents mid-winter failures.
Yes, for three reasons. First, annual maintenance preserves manufacturer warranty (which can be worth $2,000+ on heat exchanger replacements). Second, properly tuned furnaces run 5 to 12 percent more efficiently, saving $80 to $180 per year on gas. Third, combustion analysis catches cracked heat exchangers and carbon monoxide leaks that pose serious safety risks. The annual cost pays for itself even ignoring the safety value.
You can change the filter monthly during heating season, keep the area around the furnace clear, and vacuum visible dust. That covers maybe 10 percent of what a professional tune-up includes. Combustion analysis, gas pressure adjustment, heat exchanger inspection, and safety calibration all require certified equipment and TSSA gas-fitter licensing. DIY work on the gas valve, burners, or venting voids your warranty and is illegal under Ontario gas safety regulations.
We see ads as low as $59 to $79, often from contractors trying to upsell repairs once they are in your home. We strongly recommend looking at what the tune-up actually includes, not just the headline price. A $79 visual check that misses a cracked heat exchanger is a bad deal. EcoFrost charges $149 flat, no upsell pressure, written report with photos, and our techs do not earn commission on parts.
Yes. Lennox, Carrier, Trane, Goodman, Bryant, and Napoleon all require documented annual professional maintenance to keep extended warranty coverage active. The service tech logs the visit, and we provide a written tune-up record that you keep with your warranty paperwork. We pre-load this record into your customer file so warranty claims later are paperless.
September through early November is ideal. Booking before the first cold snap means short wait times (under a week typically) and avoids the November and December crush when emergency calls dominate scheduling. Spring tune-ups in April and May are a fine second option, especially if you skipped fall.
Yes. Our annual EcoFrost Comfort Plan covers one furnace tune-up, one AC tune-up, priority dispatch, and 15 percent off repairs for $389 per year. Multi-year plans run $349 per year for 3 years prepaid. We also offer single-visit tune-ups at $149 with no membership required.
