Expected Lifespan
With proper maintenance, an ASHP should last 15–20 years. Premium brands (Nibe, Mitsubishi) can exceed 25 years with good servicing history.
Key Components Lifespan
- Compressor: 15–20 years
- Fan motor: 10–15 years
- Control board: 10–15 years
- Heat exchanger: 20+ years
What Extends Life
- Annual servicing (most important factor)
- Correct installation sizing
- Good refrigerant charge maintenance
- Clean evaporator coil
What Shortens Life
- Skipping services
- Running with known faults
- Refrigerant leaks left unrepaired
