Why Choose us for Heat Pump Servicing?
Maintain system efficiency
Regular servicing keeps COP and output steady, reducing strain on compressors and extending component life.
Early fault detection
We spot refrigerant leaks, electrical wear and airflow problems early, avoiding inconvenient breakdowns and emergency call-outs.
Manufacturer-aligned records
Service reports meet manufacturer guidance and help protect warranties; we also advise on controls for smoother, safer operation.
What we check during a heat pump service
Our engineers follow manufacturer-aligned procedures tailored to domestic air-source and ground-source systems. Inspections include electrical safety checks, circulation pump performance, expansion vessel condition, thermostatic controls and, where applicable, leak tests and refrigerant charge verification. We also check source-side components (fans, coils) and the domestic distribution (flow rates, radiator or underfloor temperatures) to ensure the system is delivering as expected.
