Air Source Heat Pump Service
Regular servicing keeps an air source heat pump running efficiently, quietly and reliably. A professional service checks the system’s condition, verifies key readings, and confirms controls and settings are working as intended, helping to reduce running costs and minimise unexpected breakdowns.
More information
What an air source heat pump service covers
A routine service focuses on safe operation, performance and early fault detection. Depending on your system type and access, it typically includes:
- Visual inspection of the outdoor and indoor units for damage, corrosion, vibration or leaks.
- Cleaning and condition checks of filters, coils and condensate drainage (where fitted).
- Checks of system pressures (heating circuit), flow rate indicators and expansion vessel condition (as applicable).
- Temperature readings across the system to confirm heat transfer and identify efficiency losses.
- Review of controller settings, schedules and weather compensation so the heat pump runs steadily.
- Inspection of electrical connections, isolators and protection devices for signs of overheating or wear.
- Listening for abnormal noise and checking defrost operation and airflow clearances.
- Written notes of findings and practical recommendations for improvements or repairs.
When this service is most useful
- Your heat pump is due its annual check, or warranty terms require routine servicing.
- Running costs have crept up, rooms feel cooler, or the system cycles on and off too often.
- You have noticed unusual noises, frequent defrosting, or reduced hot water performance.
- You want reassurance ahead of winter, after building work, or before a tenancy change.
How the service is delivered
You can expect a structured visit that starts with a quick discussion of any symptoms, comfort issues and recent changes to your home or controls. The engineer then inspects the system, takes performance readings, and checks the set-up of emitters and controls so the heat pump can run at lower, steadier temperatures. Where safe and appropriate, light cleaning and minor adjustments are completed during the visit.
After the visit: keeping performance up
You will receive clear feedback on what is working well, what needs attention, and what can be optimised next. If repairs or further diagnostics are recommended, you will be able to plan the next step with clear priorities, so you can protect efficiency and reliability over the long term.
