Frequently Asked Questions

How often does a heat pump need servicing?

We recommend scheduling a full service once a year, ideally by an MCS and F‑Gas certified engineer like those at EHS. This ensures optimal efficiency, extends system lifespan, and preserves any warranty.

What does a standard heat pump service include?

Our comprehensive service includes:
Visual inspection of indoor and outdoor units
Filter, coil, airflow and refrigerant checks
Testing electrical circuits, pressure and temperature
Cleaning of internal components and optimization for performance
Advice on settings and usage after the service

How much does a heat pump service typically cost?

In the UK, the average cost for a heat pump service is around £150–£250, depending on system type. Most clients can expect an annual service fee of around £200, which includes diagnostics and system checks.

What are the most common heat pump faults?

Typical faults we diagnose and repair include:
Refrigerant leaks or low refrigerant levels
Outdoor unit icing or defrost cycle issues
Electrical failures (e.g. fan motor, compressor, controls)
Defective reversing valves or sensors
Blocked filters or airflow restrictions from coils or ducts

What symptoms indicate a heat pump may need repair?

Warning signs include:
Rising energy bills or reduced energy efficiency
Unusual noise, vibrations, or odors
Ice buildup on the external unit or coils
Fluctuating or inconsistent heating
Continuous cycling or inability to maintain temperature
Low indoor air quality or poor airflow

Can I clean or maintain my heat pump between services?

Yes — you can help ensure efficient operation by:
Keeping outdoor units clear of vegetation and at least 5 ft (≈ 1.5 m) from obstructions
Gently brushing away dust or debris on external components
Monitoring water pressure (should be around 1 bar)
Reporting any unusual sounds or performance changes promptly to EHS

Why is professional service necessary — can’t I just rely on warranty?

Warranty validity often depends on annual servicing by a qualified engineer. Regular professional service keeps your system efficient, reliable, and repairs more cost-effective in the long run. With a proper record, you’ll avoid invalidating warranty clauses and enjoy longer system life.
