Why Heat Pump Repairs Are More Common After a Calgary Cold Snap
Frequent Defrost Cycling
Cold, damp, or snowy conditions can make the heat pump enter defrost more often. A defrost fault can leave the outdoor unit iced up.
Chinook-Driven Mode Switching
Fast temperature swings can cause frequent transitions between heating, cooling, standby, and backup heat.
Handoff Strain
Dual-fuel systems depend on the heat pump, furnace, thermostat, and controls communicating correctly.
Is It Worth Repairing, or Time to Replace?
| Situation | What it often means | Next step |
|---|---|---|
| Heat pump under 8 years old | A targeted repair often makes sense if the system has been reliable. | Repair is usually worth comparing first. |
| Compressor or reversing valve failure on older unit | Major components can be expensive on aging equipment. | Request repair vs replacement options. |
| Repeated defrost cycle or handoff issues | Controls, installation setup, or system compatibility may need review. | Book whole-system diagnosis. |
| Heat pump 12+ years old with major component failure | Replacement may provide better long-term value. | Compare replacement options. |
Frequently Asked Questions
Why is my heat pump blowing cold air when it should be heating?
It may be in defrost mode, the furnace handoff may not be working, or the system may have a controls, refrigerant, or reversing valve problem.
Why does my furnace keep running even though I have a heat pump?
The thermostat may be calling for backup heat, the outdoor temperature may be below the heat pump balance point, or the heat pump may not be performing properly.
Is ice on my heat pump normal?
Light frost can be normal, but heavy ice buildup or ice that never clears can point to a defrost or refrigerant problem.
Can you repair heat pumps you did not install?
Yes. We repair many major heat pump brands and dual-fuel setups, whether we installed them or not.
What should I do if my heat pump stops working during extreme cold?
Switch to backup or emergency heat if available, then call for service. Do not keep resetting the system repeatedly if it is faulting.
