Furnace repair cost in Calgary depends mostly on which part has failed. H2O Expert Plumbing’s furnace repair page says minor repairs typically run $150 to $400, and published national estimates for single parts run from about $100 to just over $2,000.
No two furnaces fail the same way, so treat every figure below as a planning range, not a quote. Only a licensed technician who has looked at your furnace can price your repair.
- Minor furnace repairs typically cost $150 to $400, according to our furnace page.
- Single-part estimates run from $100 (flame sensor, low end) to $2,025 (several larger parts, high end).
- The part matters most, but the furnace’s age and repair history matter too.
- A new furnace’s warranty may cover parts but, in the example we read, not labour.
- Get the quote in writing before work starts.

How much does furnace repair cost in Calgary?
Our furnace page says that repair costs in Calgary “vary depending on the issue” and that minor repairs typically range from $150 to $400. It also says a clear quote comes before any work begins. That is the only Calgary price we can state first-hand, and it covers minor repairs only.
For the wider picture, Carrier’s Canadian site publishes figures from HomeAdvisor in Canadian dollars. Carrier Canada cites an average furnace repair bill of about $405, with repairs from around $87 up to $2,025 at the high end. The page shows no date and is not specific to Calgary, so read it as indicative.
We looked for an independent, regularly audited price list for Calgary furnace repairs and did not find one. That is why ranges differ from one website to the next, and why a written quote for your own furnace is the only number that counts.
What do 7 common furnace repairs cost?
The table below uses the part-by-part figures that Carrier Canada lists from HomeAdvisor, in Canadian dollars. Descriptions of what each part does are general and can vary by furnace model.
| Repair | Estimated range (CAD) |
|---|---|
| Flame sensor | $100 to $330 |
| Ignitor | $200 to $405 |
| Electronic control (circuit) board | $270 to $810 |
| Gas valve | $270 to $1,350 |
| Draft inducer motor | $270 to $2,025 |
| Blower motor | $540 to $2,025 |
| Heat exchanger | $675 to $2,025 |
1. Flame sensor: $100 to $330
In a typical modern gas furnace, the flame sensor confirms that the burner has lit. If it cannot confirm a flame, the furnace may shut down. This is often one of the lower-cost repairs on the list.
2. Ignitor: $200 to $405
The ignitor (also spelled igniter) is the part that lights the burner. Our furnace page lists “ignition failures” among the problems we diagnose, alongside no heat, strange noises, short cycling and airflow issues. An ignitor repair sits near the lower end of the table, but it still involves gas equipment, so it is a job for a licensed technician.
3. Electronic control board: $270 to $810
The control board sequences the furnace’s start-up and safety checks. When it fails, the symptoms can look like several other faults, which is one reason diagnosis comes before a quote.
4. Gas valve: $270 to $1,350
The gas valve controls the flow of gas to the burners. It is gas-line equipment, so no part of this repair is a homeowner task. The wide range reflects how much the cost can vary from one furnace to another.
5. Draft inducer motor: $270 to $2,025
The draft inducer motor helps move combustion gases out through the vent. The Alberta Safety Codes Council notes that appliances can malfunction and venting systems can fail, and that back-drafting can allow combustion gases, including carbon monoxide, into a home. Any fault in this area deserves prompt professional attention.
6. Blower motor: $540 to $2,025
The blower motor moves heated air through your ducts. When it weakens, you may notice weak airflow or unusual noise. Among the single parts in the table, it sits at the top of the range.
7. Heat exchanger: $675 to $2,025
The heat exchanger transfers heat from the burner to the air your home breathes. Natural Resources Canada says a contractor’s pre-season check should include the burner combustion and the heat exchanger, and that faults in these areas can make a system operate less safely and efficiently. A heat exchanger quote is also where the repair-or-replace question usually gets serious, which we come back to below.
What drives the price of a furnace repair?
The part is the biggest factor, and the table shows how wide the spread can be even for a single part. Beyond that, several things move the final number. The first group below is sourced. The second group is our own reading of the ranges, not a published breakdown.
What the sources show:
- Repair history. Carrier Canada says that if you are frequently repairing a furnace, replacement may be more cost-effective, and that a history of needing service, even minor repairs, may point to bigger failures to come.
- Age. The same page suggests looking more seriously at replacement once a furnace reaches 15 years old.
Our reading (inference):
- The furnace itself. Make, model and age probably affect which parts are needed and how easy they are to reach.
- What the visit includes. Ask whether the quote covers diagnosis and the repair together, or whether they are priced separately.
- More than one fault. A furnace with one failed part may reveal a second problem during the repair.
At H2O Expert Plumbing, the furnace process runs in four steps: inspect, quote, repair or install, then test and confirm. The page states that you receive a clear, upfront quote with no hidden fees and that no work starts until you approve.
Does a furnace warranty cover repair costs?
Sometimes it covers the part but not the labour. Carrier Canada says new furnaces are backed by product warranties “for the first 5-10 years of its life.”
We read one real example to see what that means. Carrier’s limited warranty for a condensing gas furnace series lists 10 years on parts if the product is registered within 90 days of installation (5 years otherwise). It states that the warranty does not cover labour or other costs for diagnosing, repairing, removing or installing parts. It also requires installation by a licensed HVAC technician and “normal” use and maintenance in line with the owner’s manual.
That is one manufacturer and one product line, so your furnace may differ. Check your own warranty document, find out whether the unit was registered, and keep your service records.
When does repairing stop making sense?
Our furnace page gives a rule of thumb: if a furnace is over 15 years old or repair costs exceed 50% of replacement cost, replacement is usually the smarter investment. Carrier Canada also points to 15 years as the age to look at replacement more seriously, while noting that a new furnace can reasonably be expected to last 15 to 30 years.
Those are guides, not verdicts. A 16-year-old furnace with a $200 fix is a different case from a 16-year-old furnace with a $1,800 heat exchanger quote. We cover the decision in more depth in our guide to repairing or replacing your furnace.
How can you keep furnace repair bills down?
You cannot prevent every failure, but a few habits reduce surprises:
- Change or clean the filter. Natural Resources Canada says to change or clean forced-air filters every three months or as they become loaded.
- Keep vents clear. The same page says to keep return-air grilles and warm-air vents clean and free of obstructions.
- Book a professional check. NRCan’s maintenance guide recommends annual pre-season check-ups by a licensed and insured contractor. See how often to service a furnace for how its guidance compares with other sources.
- Get it in writing. Alberta.ca advises getting written estimates from more than one business, and says a written estimate should include a description of the work, materials, dates, itemized costs and the total price.

Frequently asked questions
How much does furnace repair cost in Calgary?
H2O Expert Plumbing’s furnace page says minor repairs typically range from $150 to $400. Larger repairs cost more: Carrier Canada, citing HomeAdvisor, lists single-part estimates up to $2,025. Your own cost depends on the part and the furnace, so ask for a written quote before work begins.
Is a heat exchanger repair worth it?
It depends on the furnace’s age and the quote. Carrier Canada lists heat exchanger work at $675 to $2,025, and our furnace page says replacement is usually the smarter investment when a furnace is over 15 years old or repairs exceed 50% of replacement cost. Ask your technician for both numbers.
Does a furnace warranty cover labour?
Not always. In the Carrier gas furnace warranty we read, parts were covered for up to 10 years with registration, but labour for diagnosing and repairing was excluded. Your furnace’s warranty may differ, so read your own document or ask the installer.
Can I fix a furnace problem myself?
Only simple upkeep, such as changing or cleaning the filter and keeping vents clear. Natural Resources Canada says a qualified technician should handle annual maintenance. Igniters, gas valves, venting and heat exchangers involve gas and combustion safety, so they are jobs for a licensed professional.
How can I avoid surprise furnace repair bills?
Ask for a written quote, ask whether diagnosis is included, and get more than one estimate for a large repair, as Alberta.ca advises. Change filters on schedule and book a professional check before the heating season. None of this prevents every failure, but it reduces surprises.
