Best HVAC Toronto is a family-owned, TSSA-certified HVAC contractor serving Toronto and the Greater Toronto Area, with over 20 years of combined Ontario HVAC crew experience. Our annual furnace tune-up is a structured furnace maintenance visit covering every component that affects safety, combustion efficiency, and reliability through the heating season. We schedule the majority of our fall tune-ups between August and October, when demand for heating has not yet peaked, so you can secure an appointment quickly and your furnace is ready before the first cold snap. The visit runs 60 to 90 minutes. Best HVAC Toronto’s certified technicians, each holding a TSSA G1 or G2 gas licence and covered by WSIB, work through a fixed checklist rather than a general walkthrough, so nothing is left to discretion or skipped under time pressure. Every finding, measurement, and completed cleaning step is recorded on a written service report you keep at the end of the visit. ![HVAC technician removing a furnace blower assembly for deep cleaning and inspection during an annual tune-up maintenance visit in a Toronto home](/images/content/hvac-technician-removing-furnace-blower-assembly-f.webp) ### The 8-point HVAC checklist we follow on every visit **Heat exchanger and secondary heat exchanger.** We inspect the primary and secondary heat exchanger surfaces for cracks, corrosion, and deterioration. A cracked heat exchanger allows combustion gases to mix with the air circulating through your home, which is the same fault Enbridge issues red tags for. If anything looks borderline, the combustion analyzer reading helps confirm or rule out the concern rather than leaving it to a visual guess alone. **Combustion analysis.** A calibrated combustion analyzer measures flue gas composition, CO levels in parts per million, flue temperature, and combustion efficiency. This is the only reliable way to confirm the furnace is burning cleanly and safely. The readings are recorded on your service document, which is useful for warranty claims and insurance purposes. **Blower motor and wheel.** We measure blower motor amperage against the nameplate rating to catch a motor running hot before it fails mid-winter. The blower wheel is cleaned of lint and debris buildup, restoring airflow and improving system efficiency without any part replacement. **Gas pressure calibration.** Manifold and supply gas pressure are checked with a manometer and set to the manufacturer’s specification, in line with the CSA B149.1 gas code that TSSA enforces across Ontario. Pressure drift over multiple heating seasons is a common cause of poor combustion readings and nuisance lockouts. **Safety switches and limit controls.** The high-limit switch, rollout switch, and pressure switch are each tested for proper operation. A failing limit switch is one of the more common causes of furnace short-cycling and is frequently found on units that have gone without annual service. **Igniter and flame sensor.** The hot surface igniter is inspected for hairline cracks. The flame sensor is cleaned to remove the oxidation layer that builds up over one or two heating seasons, which reduces the signal the furnace control board uses to confirm a stable flame and can cause repeated lockouts if left unaddressed. **Venting and draft.** We check flue connections, venting integrity, and draft at the appliance to confirm combustion gases are leaving the building correctly. Blocked or corroded venting is one of the most common red tag causes in Toronto’s older housing stock, particularly in semi-detached homes in East York and York where a high-efficiency furnace was added years ago while the water heater remained on the chimney. **Filter inspection.** We check filter condition and provide a recommendation on timing and filter grade. A standard 1-inch disposable filter that needs replacement is swapped during the visit. Media filters and whole-home filtration systems are assessed and quoted separately. ## Why should you service your furnace every year? Toronto winters push residential furnaces hard. Most systems run continuously from November through March, with overnight lows that regularly reach minus 15 Celsius or colder in a cold year. A furnace that starts the season with a dirty blower, a borderline igniter, or burners running off-spec may survive the winter, or it may fail during a cold stretch when no-heat calls stack up and same-day appointment availability tightens. Homes running a hybrid setup, where a cold-climate heat pump handles milder days, still rely on the gas furnace on the coldest nights, so the furnace side gets the same full checklist. Annual maintenance also keeps your manufacturer warranty intact. Most manufacturers require documented annual service as a condition of coverage, and a gap in that record is grounds for a claim denial on a heat exchanger or blower motor. Our written service record is accepted by every brand we are authorized to service, including Lennox, Carrier, Trane, Bosch, Napoleon, and York. On ENERGY STAR-certified high-efficiency furnaces, which Natural Resources Canada rates by AFUE, a clean blower and calibrated burners keep the unit running close to the efficiency you paid for. A clean combustion analysis gives you documented proof that your furnace is burning safely if an Enbridge meter reader or a home inspector questions the appliance condition. If the inspection turns up a needed furnace repair [/furnace-installation-repair/ →](/furnace-installation-repair/) , our technicians carry the common parts on the van. Igniter replacements, flame sensor swaps, and pressure switch replacements are usually completed on the same visit. Larger repairs are quoted in writing before we proceed. If you need emergency service at any hour, our line is staffed 24/7 at 647-254-4113. ## Booking fall maintenance across Toronto and the GTA From post-war bungalows in Scarborough [/service-areas/scarborough/ →](/service-areas/scarborough/) and Etobicoke [/service-areas/etobicoke/ →](/service-areas/etobicoke/) to two-storey detached homes and townhouses in Vaughan [/service-areas/vaughan/ →](/service-areas/vaughan/) , Markham [/service-areas/markham/ →](/service-areas/markham/) , and Mississauga [/service-areas/mississauga/ →](/service-areas/mississauga/) , the Best HVAC Toronto crew services furnaces across the full Greater Toronto Area.

DDenise O.Brampton FAQ ## Furnace Tune-Up questions, answered ### What does a furnace tune-up include? expand\_more Our annual furnace tune-up covers a heat exchanger visual inspection, combustion analysis with documented CO readings, blower motor amperage check, blower wheel cleaning, gas pressure calibration, safety switch and limit control testing, igniter and flame sensor service, venting and draft check, and a filter inspection. You receive a written service record with all findings and measurements at the end of the visit. ### How much does a furnace tune-up cost in Toronto? expand\_more Our tune-up visits run $150 to $220 (2026 rates) depending on the scope of work. The standard inspection and combustion check starts at $150. The full-service visit, which adds blower deep cleaning, gas pressure calibration, and igniter and flame sensor service, is $190. Maintenance plan members receive the full-service scope at the member rate. Any repair found during the visit is quoted in writing before we proceed. ### How long does a furnace tune-up take? expand\_more A full furnace tune-up takes 60 to 90 minutes. The time covers the safety inspection, blower and flame sensor cleaning, gas pressure calibration with a manometer, and the combustion analyzer test. If a part such as an igniter or pressure switch needs replacing, it is usually done on the same visit, since common parts are carried on the van. ### When should I schedule my annual furnace tune-up? expand\_more We recommend booking between late August and October, before the heating season begins. That timing gives you an appointment without the urgency of a no-heat call, and your furnace starts the season freshly serviced. We also accept tune-up calls during the heating season if your furnace is showing early signs of trouble, such as short-cycling or unusual noise. ### How often should a furnace be serviced? expand\_more Once a year is standard, and most manufacturers require documented annual service as a condition of the warranty. Annual maintenance catches igniter wear, sensor oxidation, gas pressure drift, and blower buildup before they become failures. If your furnace is over 15 years old or has had repeated service calls, your technician will note that during the visit. ### Can a tune-up prevent an Enbridge red tag? expand\_more Annual maintenance addresses several of the most common red tag causes: heat exchanger condition, venting integrity, and combustion CO levels. A clean combustion analysis at the end of the visit gives you documented proof the furnace is burning safely, which is useful if a meter reader or inspector questions its condition later in the season. ### Will you replace my furnace filter? expand\_more We inspect the filter and give you a condition report and recommendation. Standard 1-inch disposable filters are replaced during the visit when needed. Thicker media filters and whole-home filtration systems are assessed and quoted separately. We also advise on filter grades, since a filter that is too restrictive for your blower is a common cause of airflow problems and short-cycling. ### What is a combustion analysis and why does it matter? expand\_more A combustion analyzer measures flue gas composition including carbon monoxide in parts per million, flue temperature, and combustion efficiency. A visual inspection cannot detect elevated CO or a burner running rich. The analyzer readings tell you whether the furnace is burning cleanly and how close its efficiency is to the rated AFUE. We record the values on your service document every visit. ### Should a 40-year-old furnace be replaced? expand\_more In most cases, yes. A 40-year-old furnace is well past the typical 15 to 20 year service life, often runs at 60 to 65 percent efficiency compared with 95 percent or higher for a modern condensing unit, and carries a higher risk of a cracked heat exchanger and an Enbridge red tag. A tune-up can confirm whether it is still safe for this winter, and we provide free on-site estimates for a replacement with a written quote before any work begins. ### How much does a new furnace cost in Ontario? expand\_more A new furnace installed in Toronto and the GTA costs $3,500 to $7,500 in 2026, depending on the efficiency tier, size, and venting work required. ENERGY STAR-rated high-efficiency units may qualify for rebates, and financing is available on approved credit, including zero-down lease-to-own programs for qualifying installations. All installations include a 2-year labour warranty plus 5 to 10 years of manufacturer coverage. ### Are there furnace maintenance plans that lower the yearly cost? expand\_more Yes. Customers who service their furnace with us annually receive a discounted rate on the following year's visit. For a more structured arrangement, our maintenance plan provides the full-service tune-up at a reduced rate, priority fall scheduling, and discounts on repairs and other HVAC services across Toronto and the GTA.
