Air source heat pumps are incredibly efficient heating systems—when properly maintained. But how often should you service your ASHP, and what happens if you don’t?
Annual Servicing is Essential
The simple answer: your air source heat pump should be serviced once a year, ideally in autumn before winter demand increases.
Unlike traditional boilers, heat pumps are complex systems with refrigerant circuits, electrical components, and outdoor units exposed to the elements. Regular servicing ensures everything works as it should.
Why Annual ASHP Servicing Matters
Without annual servicing, your heat pump can lose up to 25% efficiency. That means:
- Reduced heating performance when you need it most
- Shorter system lifespan
- Risk of voiding your manufacturer’s warranty
- Potential breakdowns during cold weather
What’s Included in an ASHP Service?
A professional air source heat pump service includes:
✅ Full system health check – Identifying potential issues before they become problems
✅ Refrigerant level inspection – Ensuring optimal heat transfer efficiency
✅ Performance optimization – Calibrating settings for maximum efficiency
✅ Filter cleaning and replacement – Maintaining airflow and system efficiency
✅ Electrical safety check – Ensuring all connections are safe and secure
✅ Detailed efficiency report – Showing how well your system is performing
When to Book Your ASHP Service
The best time to service your air source heat pump is September to October—before winter heating demand begins. This ensures:
- Your system is ready for winter
- Any issues are fixed before cold weather
- You’re not competing with emergency callouts during peak season
- Your warranty remains valid
Signs Your Heat Pump Needs Servicing
Between annual services, watch for these warning signs:
- Unusual noises from the outdoor unit
- Reduced heating performance
- Higher than normal energy bills
- Ice buildup on the outdoor unit (outside of defrost cycles)
- Error codes on your control panel
If you notice any of these, book a service check immediately.
