Annual ASHP servicing
System-specific servicing can include outdoor-unit condition, coils and fans, filters and strainers, system pressure and flow, glycol protection, controls, cylinder safety and service reporting where applicable.

Existing heat pump support
ASHP servicing, fault finding and repairs by experienced heating engineers
Air source heat pump faults are not always caused by the outdoor unit. Problems can come from poor flow, blocked strainers, pumps, valves, controls, weather compensation, system pressure, glycol protection, cylinders or commissioning settings. Our ASHP service and repair work considers the complete wet heating and hot-water system so the cause is investigated properly.
Fault investigation
For fault codes, poor heating, loss of hot water, unusual noise or repeated problems, send us the make, model, postcode and symptoms so we can assess the appropriate next step.
Performance problems
We can investigate wider system factors such as circulation, emitter performance, control settings and hydraulic issues where these form part of the problem.
Seasonal commissioning
Moved into a property with an ASHP or unsure how it has been set up? We can check operating settings, heating schedules, hot-water control and system condition, then explain how to use the controls properly.
Bivalent & hybrid systems
We also work on heat pumps combined with boilers and other heat sources, including bivalent systems where the ASHP and boiler are designed to work together in colder weather.
ASHP breakdown support
No heating, no hot water, repeated alarms or a system that will not run correctly? We can investigate the fault, reset only where appropriate, and identify whether the issue is controls, hydraulics or the heat pump itself.

ASHP service questions
Air source heat pump servicing FAQs
How often should an air source heat pump be serviced?
Annual servicing is a sensible interval for most domestic ASHP systems, particularly where the manufacturer or warranty documentation specifies routine maintenance. The exact checks depend on the make, model and system design.
Do you repair heat pumps as well as service them?
Yes. Envirowarm carries out ASHP fault investigation and repair work as well as planned servicing. We work on the wider heating system too, which is important when the fault is caused by flow, controls, pumps, valves, strainers or hot-water components.
Which ASHP brands do you work on?
Our recent work includes Mitsubishi Ecodan, Samsung, LG, Hitachi and Vaillant systems, alongside other air-to-water heat pumps. Send us the make, model and fault symptoms before booking so we can assess the job correctly.
Can you service an ASHP if I have just moved into the house?
Yes. We can carry out a service and seasonal commissioning check, review the controls and settings, and explain how the heating and hot-water system is intended to operate.
Do you cover areas outside Hull?
Yes. We cover Hull and surrounding East Yorkshire areas including Beverley, Cottingham, Hessle, Willerby, Anlaby, Brough, Hedon, Hornsea and villages across the region. Specialist work may also be considered further afield.
What should I send before an ASHP repair visit?
Please send the heat pump make and model, postcode, any fault code shown on the controller and a short description of the symptoms. Photos of the controller and outdoor unit can also help us identify the system before attendance.
Need an ASHP engineer?
Tell us the make, model and what the system is doing
Include your postcode, fault code if present, and a short description of the problem. That gives us a much better starting point before attendance.
