Furnace Maintenance Cost: 9 of 20 GTA Companies Post It

Nine of the 20 GTA heating companies we checked publish a price for a one-time furnace tune-up. Taking each one's cheapest visit, those nine prices run from $90 to $179, and the middle of the set is $121.68. Seven more publish only a plan price, and four publish no price for their own work at all. The gap matters, because a year on a $9.99 a month plan works out to $119.88, and Reliance sells a single tune-up for $119.00. Below is what each company publishes, what a plan actually buys, and why your furnace warranty rather than Ontario law is what puts a service call on your calendar.

What a furnace tune-up costs in the GTA

We checked 20 HVAC companies serving the GTA on September 7, 2026. Between them they cover Toronto, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Pickering and Ajax. For each one we read its own furnace maintenance page, and its plan, pricing, specials or coupon page where it has one. A company counts as publishing a price only when a dollar figure sits on its own website. Nine of the 20 clear that bar.

Nine companies, ten rows: Reliance sells two tiers, and Megacity prints a range. Take one price per company, the cheapest visit each advertises that covers a furnace. For Megacity that is the $120 low end of its range. The set is $90, $99, $119.00, $120, $121.68, $149, $150, $160 and $179. With nine prices, the middle one is the fifth: $121.68.

Three of the nine are floors rather than flat prices. AirPoint says its visits start at $90, EcoFrost that its tune-up starts at $149, and GTA ClimateCare that its tune-up starts at $160. Two are offers rather than standing rates. Airtronic's $99 sits on a page headed "SPECIAL OFFER COUPONS". Climate Experts' "$150 Home Check Up Special" covers a furnace or A/C tune-up, and the fine print on its offer image reads "without a Maintenance Plan". The page adds "Cost applied toward any recommended repairs". Megacity gives a range, so only Reliance, City Home Comfort and Furnace King print a figure that reads as the price.

Four of the nine say tax is extra. AirPoint prints "$90 (+HST)", Reliance footnotes "Plus applicable taxes", GTA ClimateCare prints "+ HST", and Furnace King says "Prices displayed do not include HST". Airtronic, City Home Comfort, Megacity, EcoFrost and Climate Experts give a bare number and say nothing, so the figure on the screen may not be the figure on the invoice. Ask before you book.

Eleven of the 20 will not price a single visit

Seven companies price a maintenance plan but never price a single visit. Enercare, Advantage Airtech ClimateCare, Spring Home, Maple Air, Dr HVAC, Tempasure and Laird and Son all fall in that group. If you only want one visit this autumn, none of them will tell you what it costs without a phone call.

Four more publish no maintenance price of any kind. Cozy Comfort Plus, Cozy World, AtlasCare and Belyea Brothers describe the work and ask you to request a quote. We looked past the service page in each case. Cozy World prices a repair call at $99 but not a tune-up. AtlasCare's promotions page prices drains and equipment, not maintenance. Belyea Brothers publishes a service plan agreement whose price line is left blank for the customer.

Four of the nine put the number somewhere other than the obvious page. AirPoint's price is on its Toronto furnace maintenance page, not in the cost guide that ranks for the search. GTA ClimateCare's is on ai.gtaclimatecare.com, a machine-readable pricing subdomain it links from every page of its main site; the WeCARE plan page itself carries no figure. Climate Experts' sits on its offers page, not its maintenance page, and Airtronic's $99 visit is on its coupons page.

What a plan really costs once you multiply it out

Fourteen of the 20 publish a plan price. Thirteen are in the table below, and Airtronic's follows it.

Monthly pricing hides the yearly number, so do the multiplication. Enercare's Heating Maintenance Plan for furnaces is $9.99 a month plus HST and runs for 12 months. That is 9.99 x 12 = $119.88 before tax, for one annual 22-point inspection. Advantage Airtech charges the same $9.99 a month and prints the yearly figure on its own page as $119.88, so the arithmetic is the industry's, not ours. Its plan also carries a one-time initial precision tune-up fee of $59.99 to join, so a first year there is 59.99 + 119.88 = $179.87.

Airtronic prints its Heating Maintenance Plan at $14.99 a month for an annual visit with an up to 21-point inspection. That is 14.99 x 12 = $179.88 a year, and the page states no tax or term.

Reliance is the one to read closely. It prints "$9.99" with "(12-month term)" beside it and no period on the figure itself. Its own product page settles the question: bundling this plan with the protection plan saves "$2.99/month compared to purchasing them separately", which only works if the $9.99 is monthly. Twelve of those is the same $119.88, against $119.00 for the 12-point tune-up Reliance sells outright. A year on the plan costs 88 cents more than one visit from the same company.

Seven companies publish both a plan and a single-visit price, and on the printed figures five of those seven plans cost more in the first year. Furnace King charges $179 plus HST for a visit off plan. Join the monthly plan and that visit is $99 today, then $10.99 a month, so year one is 99 + 131.88 = $230.88 before HST, because 10.99 x 12 = $131.88. From year two the monthly fee alone is $131.88, which is less than $179.

AirPoint is the widest gap, though it is not a like-for-like swap. A visit is $90 plus HST, while its AirProtect plan charges $149 for the maintenance on sign-up and then $23.99 a month to cover repairs as well. Year one is 149 + 287.88 = $436.88, because 23.99 x 12 = $287.88. You are buying repair cover, not a cheaper tune-up.

Airtronic's plan year, $179.88, tops its $99 coupon. Climate Experts' plan tops its $150 check-up at either yearly figure its page prints, though it buys two visits.

The two plans that win do so on floors, not flat prices. EcoFrost's Annual Comfort Plan is $229 for a furnace and an air conditioner tune-up, against 149 x 2 = $298 if you bought both separately. The $149 is a "starting at" price. The $229 is printed under "Flat-rate pricing" with no floor language, so only one side of that comparison can move. GTA ClimateCare's plan starts at $9.99 a month, or $119.88 a year, against a tune-up starting at $160.

One page in the set disagrees with itself. Climate Experts advertises its bi-annual furnace and air conditioner agreement at $29.95 plus HST a month, which is 29.95 x 12 = $359.40 a year, and on the same page invites you to join "FROM $239.00 PER YEAR". Ask which one applies to you before you sign.

Tempasure puts a number on what it thinks a single visit is worth. Its page prices two maintenance visits a year at a "current value $249/each" and sells the combined plan at $26.25 a month, which its own page totals as $315 plus HST. That $249 is well above every published one-visit price in this study.

A 27-point tune-up is not bigger than a 12-point one

Ten of the 20 companies publish a checklist size. They do not describe the same job in the same way, and the counts are not comparable.

Two of those numbers need a footnote. Maple Air's eight is the claim in its heading, and the list that renders beneath the heating plan is the cooling one, so nobody can check the eight. Cozy Comfort Plus explains what a point count really means: "Each check applies only when the installed system includes that component", and "A routine tune-up does not confirm the condition of concealed ductwork or inaccessible internal parts". A 27-point list can shrink on a simple furnace, and a 12-point list can cover everything yours has.

Ask what the visit measures rather than how many boxes it ticks. Enercare says it checks the whole heating system for "problems with energy efficiency, carbon monoxide leaks, air quality, or worn-out and faulty materials". Climate Experts lists a burner assembly clean and a gas pressure inspection in its fall heating visit. Reliance describes its 12-point service as an inspection of 12 major components and its 21-point service as testing and cleaning. EcoFrost promises a written report and Enercare a HomeCare Report.

Ontario does not set an interval. Your warranty does

Ontario's rule for gas appliances is O. Reg. 212/01, Gaseous Fuels, made under the Technical Standards and Safety Act, 2000. Section 15 says an owner or user of a gas appliance shall ensure it "is maintained in a safe operating condition". That is a real duty and it applies to your house.

What the regulation does not do is name a frequency for you. We searched the whole consolidated text, which is current from May 15, 2015, for "annual", "once a year", "12 months", "each year" and "yearly". There are zero matches. Two sections do set a 10-year interval, and neither binds a homeowner. Section 16 requires the gas distributor to have inspected the appliance within the previous 10 years. Section 17 puts an evaluation and inspection duty on the owner of an industrial, institutional or assembly building.

The annual habit comes from the equipment makers. Lennox opens its limited warranty, which applies in Canada, with the line "Failure to maintain equipment will void this limited warranty". The same document adds that proof of prior maintenance may be required when you claim. Rheem's gas furnace warranty excludes any failure caused by a "failure to properly install, operate or maintain Covered Equipment in accordance with the Manufacturer's instructions".

Carrier states the condition and then supplies the interval. Its warranty for a non-condensing gas furnace requires that "Installation, use, care, and maintenance must be normal and in accordance with instructions contained in the Installation Instructions, Owner's Manual and Company's service information". Carrier's own furnace manual then says "A qualified service person should inspect the furnace once a year", and asks for the burner compartment and the vent system to be inspected "before each heating season". Under the Canadian gas code, CAN/CSA B149, that manual notes the vent system should be checked once a year by qualified service personnel.

So keep the invoices. The warranty asks for proof of maintenance, and a dated receipt is the proof.

How to buy one without overpaying

Get the price in writing before the technician arrives, and ask whether it includes tax. Four of the nine companies say tax is extra and five are silent, so the question is not rude. Ask too whether the number is a floor: three of the nine are "starting at" prices, one is a range and two are offers.

Ask what happens if the visit finds a fault. Every company here sells the tune-up and the repair separately, and a GTA furnace repair is not small. AirPoint's cost guide puts a blower motor at $400 to $1,200 and a heat exchanger at $1,000 to $2,500, at which point it says replacing the furnace is often the better call.

Book before the cold arrives, because Carrier's manual asks for the check before each heating season. Then do the plan maths yourself. Multiply the monthly figure by 12, add any joining fee, and compare that with one visit at the published price from the same company.
