Servicing & fault investigation
A whole-system heat pump service, not just a quick visual inspection
The heat pump is only one part of the heating system. Depending on the model and installation, we can inspect the outdoor unit, hydraulic circuit, filters and strainers, system pressure and flow, glycol protection, cylinder safety devices and controls. If you have a fault code, poor heating, unusual noise or another problem, include the symptoms when you contact us so we can assess the next step.
Outdoor unit
Coil and fin condition, appropriate cleaning, fan operation, casing condition, visible signs of oil leakage or physical damage, pipe insulation and condensate drainage.
Hydraulic system
Water filters and strainers, system pressure, flow rates, valves, pumps and removal of trapped air that could restrict circulation.
Glycol / anti-freeze
System fluid protection can be tested with the appropriate equipment to assess glycol or anti-freeze concentration where used.
Cylinder safety
Relevant hot-water-cylinder safety devices, including temperature and pressure relief arrangements where fitted and within scope.
Controls
Controller settings, weather compensation and heating schedules can be reviewed so the system is set appropriately for the property.
Service record
A service report can document checks carried out, system condition and any recommendations requiring attention.

Common questions
Heat pump servicing FAQs
How often should my heat pump be serviced?
Annual servicing is common, but always follow the manufacturer’s service schedule and any warranty requirements for your specific model. If you have moved into a recently built home, you can also register your new-build heating system with Envirowarm so we can record the system details and service anniversary.
Do you service Mitsubishi Ecodan systems?
We have genuine Mitsubishi Ecodan service experience, including the recent PUZ-WM50VHA R32 system in Immingham. Suitability depends on the specific model and installation.
Do you service air source and ground source heat pumps?
Yes, Envirowarm works with suitable air source and ground source systems. We have project experience including LG air source and NIBE ground source equipment.
Why check glycol or anti-freeze?
Where glycol or anti-freeze is used, its concentration can form part of system protection against low temperatures. The correct requirement depends on the installation and manufacturer guidance.
Do you service heat pumps in Hull and East Yorkshire?
Yes. Envirowarm provides suitable heat pump servicing across Hull, East Yorkshire and selected parts of North Lincolnshire. Our genuine local project work includes LG air source heat pump servicing in Kingswood, Hull and Mitsubishi Ecodan servicing in Immingham.
Can weather compensation be checked during a heat pump service?
Where applicable, we can review controller settings and weather compensation as part of servicing. The appropriate settings depend on the property, emitters, system design and the manufacturer’s controls.
What information should I provide when booking a heat pump service?
Please provide the heat pump manufacturer and model if known, your postcode and details of any faults, warning messages or unusual behaviour. This helps us assess the system before attendance.
