A Guide to the Best Furnace Repair in Toronto

Did your home furnace suddenly break down without any warning? In that case, you need to hire contractors who can provide you with the best furnace repair in Toronto.

To save you time and effort, we’ve already listed our top picks for the most experienced and reliable furnace contractors in the city. But before we proceed with our list, we’ll walk you through the cost of furnace repairs, the type of repair services offered, and commonly asked questions about furnace repairs.

Without further ado, let’s start!

The Cost of Furnace Repair in Toronto

When looking for a furnace contractor in Toronto, you need to keep in mind that the actual repair cost will be based on two things: the part that needs to be repaired/replaced and the coverage of your insurance.

Currently, the average cost of furnace repair in Toronto is somewhere between $200 to $400 if a single part needs to be repaired. If multiple parts need to be repaired, then expect to pay more.

Your actual repair cost will depend largely on which parts need to be replaced or fixed. However, the cost of furnace parts differs by brand, so it’s really hard to give an actual estimate.

Here’s a table of the common furnace parts and their estimated costs to give you an idea of how much you can expect to pay:

Furnace PartExpected Cost
Thermostat$75 to $200
Heat exchanger$150 to $275
Electronic ignition or pilot light$250 to $375
Heat exchanger replacement$1,500 to $3,300+
Flame sensor$80 to $250
Blower motor$140 to $440
Transformer$100 – $175
Relay switch$150 – $300
Condenser and evaporator coil$600 – $2,000

If your furnace comes with insurance, then you might be able to escape the expenses of having it repaired. Most furnaces come with either of two types of insurance:

Parts warranty: This usually covers the cost of replacing and repairing defective furnace parts for at least five years. Some warranties cover only defective parts due to manufacturing issues.

If you bought an extended warranty, their coverage may last more than five years. Most manufacturers offer limited warranty on the heat exchanger because it’s the most expensive furnace part.

Labor warranty: Contractors who installed your furnace will usually offer at least a one-year of labor warranty that covers the cost of labor of repairing a faulty furnace.

Customer Reviews

Take a look at some of these comments shared on Google Reviews:

“Furnace broke down last week.  Had four quotes for either variable fan motor repair or outright furnace replacement.  Furnace Pro came in with a competitively priced option on the new furnace because they scoped the work correctly vs the other companies.  Furnace Pro was able to provide costs for the repair and replacement.  They also were able to provide next day service for either option.  The decision to replace the furnace resulted in a new install.  The crew that came to install was friendly, professional, clean and timely.  Would recommend this company to my friends and family.”

“Ash did a great job on the furnace maintenance. He did not rush through but ensured that all parts were in good working order. Then he took his time to explain everything he did and what areas needed his attention. The job took less than 40 minutes and the price was reasonable. Thanks for your professionalism.”

I hope Tony is the tech I get every year for any service or maintenance calls.”

“Today Reliance’s technician (Brad) came and fixed my furnace issues in less than 45 minutes. He was very good and identified the issue very quickly and logically. He replaced parts and after that the furnace is working very fine. I have a maintenance contract for my furnace, air conditioning and plumbing and I am very satisfied with Reliance’s services.

Customer Reviews

A Plus Quality Inc. has an average rating of 4.8 out of 5 on Google Reviews, making it one of the best-rated furnace contractors in Toronto. Here are some comments shared by customers:

“A+ from beginning to almost the end. Final cleanup was quite average. Overall experience still good. Very happy with the new furnace. Will have to wait till warmer/hotter weather to see how well the new AC works.

“First experience was on New Year’s Day, 2020, when furnace stopped. Called A-Plus and they had a rep (Jack) out quickly. He did some troubleshooting. He wasn’t giving BS. Gave me options on repairing or replacing. Non-biased, no pressure. I chose replace and it was done the next day. Good experience all around. Second experience was early March, 2021 when a harsh chemical smell emanating from the furnace room, and pushed through the HVAC venting, permeated the house. Very concerning. Was late night, called A-Plus, immediately answered and suggested some safety moves for the evening. Booked a visit for the morning. Jack again came and assessed the issue and advised where the smell came from (outside). Again, very professional, quick, no BS, good guy. Completely satisfied with the service after often being given the BS treatment from other service providers for the house. Would definitely recommend.”
