Regular furnace service is essential to keeping your heating system safe, efficient, and reliable—especially during Toronto’s harsh winters. But what does furnace service actually cost in 2025–2026, and what should homeowners expect when budgeting for repairs, annual maintenance, or emergency service?
This updated guide breaks down current furnace service pricing in the GTA, the factors that influence cost, and practical ways to save money while extending the lifespan of your heating system.
Average Furnace Service Costs in Toronto (2025–2026)
Furnace service pricing depends on whether you’re booking a routine maintenance visit, diagnostic appointment, or a repair. Here is what homeowners across Toronto, Vaughan, Richmond Hill, Markham, and North York typically pay.
Routine Furnace Tune-Up / Maintenance
$120–$250
A standard maintenance visit includes system cleaning, inspection, safety checks, airflow testing, and filter replacement if provided. Annual furnace maintenance is the best way to prevent unexpected breakdowns and ensure your system operates safely throughout winter.
Diagnostic Service Call
$90–$150
This covers the technician’s time to determine what is wrong with your heating system. Many HVAC companies credit the diagnostic fee toward the final repair cost if you proceed.
If your system keeps turning on and off without heating properly, see our guide on furnace short cycling to understand what might be happening before your appointment.
Furnace Repair Costs
Repair pricing varies based on the part, labour, furnace age, and the severity of the issue. If you’re experiencing inconsistent heat, loud noises, or repeated shutdowns, scheduling professional furnace repair early can prevent the issue from worsening and reduce the risk of a no-heat situation.
Below is a more detailed breakdown for 2025–2026.

Factors That Affect Furnace Service Costs
1. Type of Furnace
Gas furnaces involve ignition systems, burners, venting, and additional safety testing, making servicing more complex and sometimes more costly than electric furnaces. To get a sense of the most frequent issues homeowners face, review our article on common furnace problems in Toronto.
2. Age of the Furnace
Older furnaces tend to:
- Break down more frequently
- Require parts that are harder to find
- Consume more labour time
- Carry a higher risk of issues like furnace blowing cool air
If your furnace is 15–20+ years old, repair bills typically increase each winter. Many homeowners with aging systems prefer upgrading to a high-efficiency model through professional furnace installation, especially when major components like heat exchangers fail.
3. Complexity of the Repair
Simple repairs (like cleaning a sensor or replacing a filter) are affordable. More complex jobs—such as blower motor replacement or control board failure—require more time and specialized components, which increases the total cost.
4. Time of Service (Regular vs. Emergency)
During extremely cold periods, Toronto HVAC companies receive a surge of no-heat calls. Emergency appointments or after-hours service often come with an added premium. If your furnace is repeatedly failing to ignite, refer to our guide on why your furnace isn’t igniting for early signs to watch for.
5. Location and Technician Availability
Service costs vary slightly across the GTA depending on travel distance, technician availability, and overall seasonal demand. Homes further from central Toronto may experience small adjustments in diagnostic or travel-related fees, but a reputable company will always explain pricing upfront.
Annual Furnace Maintenance Costs (2025–2026)
Most HVAC companies in Toronto offer furnace cleaning and inspection packages ranging from $120 to $300. Routine furnace maintenance is the most reliable way to prevent mid-season breakdowns, reduce repair costs, and keep your furnace running efficiently.
A proper annual maintenance visit typically includes:
- Cleaning burners, sensors, and internal components
- Replacing the furnace filter
- Checking venting and airflow
- Testing ignition and safety controls
- Inspecting the heat exchanger
- Lubricating moving parts
- Completing a system tune-up
If you want to perform simple upkeep yourself between visits, start with learning how to change your furnace filter correctly.
Add-On Maintenance Services
Duct Cleaning
$250–$500
Duct cleaning is optional but recommended if you’ve recently renovated, own pets, or notice dust buildup or airflow issues.
Humidifier Cleaning / Service
$30–$80 add-on
Helps prevent mould, scaling, and humidity imbalance during winter.
