If your heat pump isn't performing like it used to, you're probably wondering whether it's worth repairing or if it's time to replace it.
The answer depends on its age, the fault, and how much the repair will cost compared with the value of a newer, more efficient unit.
Heat Pump Age Guide
Less than 5 years old
Most problems are worth repairing.
Units under warranty may have parts covered, and repairs are usually the most economical option.
5–10 years old
This is the grey area.
A simple repair such as replacing a fan motor, sensor or PCB may still represent good value.
10–15 years old
It depends on the fault.
If expensive components such as compressors or refrigerant systems require major work, replacing the unit often makes better financial sense.
Over 15 years old
Modern heat pumps are generally quieter, more efficient and offer improved features such as Wi-Fi control and better air filtration.
If your existing unit requires significant repairs, replacement is often the better long-term investment.
Common Faults
Dirty indoor coil
A professional clean can often restore airflow and efficiency.
Refrigerant leak
Leaks can sometimes be repaired, but the cost depends on where the leak is located.
Faulty PCB
Electronic control boards can often be replaced if parts remain available.
Compressor failure
One of the more expensive repairs.
Depending on the age of the unit, replacement may be the better option.
Signs Replacement May Be Worthwhile
- Increasing repair frequency
- Higher power bills
- Poor heating performance
- Excessive noise
- Parts becoming unavailable
- Rust or corrosion
Benefits of Replacing
Newer models often provide:
- Lower running costs
- Better heating performance
- Quieter operation
- Improved air filtration
- Smart phone control
- Longer warranty
