What Does Furnace Repair Cost in Calgary?
Furnace repair costs in Calgary vary widely depending on what failed, the age of the unit, and whether parts need to be ordered. Here are honest 2026 price ranges based on common repairs Alberta Home Services performs.
| Repair Type | Typical Cost (CAD) | Notes |
|---|---|---|
| Diagnostic / service call | $89–$150 | Usually applied toward repair cost |
| Igniter replacement | $200–$350 | Most common furnace failure in Calgary |
| Flame sensor cleaning/replacement | $150–$275 | Often causes short-cycling |
| Blower motor replacement | $400–$800 | Higher for variable-speed motors |
| Heat exchanger replacement | $800–$1,500+ | Consider replacing furnace if unit is 15+ years |
| Control board replacement | $400–$900 | Depends heavily on furnace brand |
| Inducer motor replacement | $350–$700 | Common on high-efficiency furnaces |
| Gas valve replacement | $300–$600 | Requires licensed gas fitter |
| Capacitor replacement | $150–$300 | Quick repair, common on older units |
| Pressure switch replacement | $175–$325 | Often confused with other issues |
What Drives Furnace Repair Costs Higher?
Several factors push repair costs above the typical ranges:
- Furnace age: Parts for furnaces 15+ years old can be discontinued or require special ordering, adding 1–2 weeks and $100–$300 in parts markup.
- High-efficiency vs. standard: 95%+ AFUE condensing furnaces have more components (secondary heat exchanger, condensate drain system) and higher parts costs.
- Emergency / after-hours service: Expect a 25–50% premium for same-day or weekend calls in Calgary winters.
- Multiple failures: A furnace that has failed once is more likely to have secondary issues, especially in units 10+ years old.
The 50% Rule: If the repair costs more than 50% of a new furnace, replacement is almost always the better financial decision — especially if the unit is over 10 years old.
When Does Repair Stop Making Sense?
Repair makes sense when the furnace is under 10 years old, the repair is a single component failure under $500, and the rest of the system is in good condition. Replacement becomes the better call when:
- The furnace is 15+ years old
- The heat exchanger is cracked (a safety issue — carbon monoxide risk)
- You've had two or more repairs in the past two years
- Heating bills have increased noticeably without a change in usage
- The repair cost exceeds $1,000 on an older unit
New Furnace Cost in Calgary (2026)
| Efficiency | Unit + Installation | Best For |
|---|---|---|
| 80% AFUE (standard) | $2,800–$4,200 | Older homes with existing venting |
| 92–96% AFUE (mid-efficiency) | $3,500–$5,500 | Most Calgary homes |
| 97–98.5% AFUE (high-efficiency) | $4,500–$7,500 | Tight builds, maximum savings |
Does Alberta Have Furnace Rebates?
Yes. The Canada Greener Homes Grant and Enmax efficiency programs have offered rebates up to $5,000 for high-efficiency furnace upgrades. Program availability and amounts change — call Alberta Home Services or check NRCan's current program page for the most current amounts before booking.
Alberta Home Services tip: Book your furnace tune-up in September before the cold sets in — technicians are available, wait times are shorter, and you catch problems before you need heat urgently.
