How Long Does a Heat Pump Last? Lifespan Guide for Ontario Homeowners
A well-maintained heat pump in Scarborough and the GTA lasts 15–20 years. Here is what affects lifespan and how to maximize it.
Average Heat Pump Lifespan by Component
- Compressor — 15–20 years (most critical component; failure often means replacement)
- Outdoor fan motor — 12–18 years
- Reversing valve — 15+ years
- Capacitors — 5–10 years (common repair)
Factors That Shorten Heat Pump Life in Ontario
- Skipping annual tune-ups (refrigerant leaks go undetected, compressor runs in distress)
- Dirty coils (blocked heat transfer forces compressor to work harder)
- Low refrigerant charge (compressor overheats)
- Improper sizing (oversized systems short-cycle; undersized ones run continuously)
Signs Your Heat Pump Needs Replacement (Not Repair)
- System is 15+ years old with a compressor failure
- Running on R-22 refrigerant (no longer manufactured)
- Repair cost exceeds 40% of replacement cost
