Heat pump repairs in High Wycombe: what to expect
Whoever installed your heat pump, aftercare can be arranged in High Wycombe. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Outdoor units in exposed spots around High Wycombe can ice more heavily, so siting is checked as part of any icing fault. Repairs in High Wycombe that need a part ordered are explained and priced before the engineer leaves.
When a heat pump shows an error, loses pressure or stops heating, an engineer diagnoses the cause and explains the repair and its cost before fixing it.
- Heat pumps showing an error code or fault light
- Systems losing pressure or needing frequent topping up
- Rooms or hot water not getting warm enough
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- Supply and fitting of replacement parts
- System refill, venting and recommissioning after the repair
- Testing of sensors, pumps, valves, pressures and electrics
- Fault-finding visit at a rate agreed before attending
Across High Wycombe and Buckinghamshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
Grants and rules for heat pumps in England

Designing for High Wycombe's winters
On the shortest day High Wycombe gets about 7 hours 48 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Heat pump repairs in High Wycombe: questions
How much does a visit cost in High Wycombe?
The rate for a service or fault-finding visit is agreed before anyone attends. Any repair is priced in writing before parts are ordered, so you decide before work goes ahead.
Do you also cover Marlow?
Yes. We arrange heat pump servicing and repairs in Marlow, which is about 4 miles south of High Wycombe, and across Buckinghamshire.
Can you work on a heat pump in High Wycombe that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in High Wycombe, whoever fitted them. Tell us the make and model when you get in touch.
Can you repair a heat pump installed by another company?
Yes. We carry out fault-finding and repairs on heat pumps installed by other companies, including monobloc and split systems. Tell us the make, model and approximate age when you get in touch, plus any error code shown. If the system is still under the manufacturer's warranty, it may be quicker to contact the original installer or manufacturer first.
Why is my heat pump showing an error code?
An error code is the heat pump's way of reporting a problem it has detected, such as low water flow, a sensor reading out of range or a communication fault between units. Note the code and check the manual, as some codes clear after a simple reset or pressure top-up. If it returns, an engineer can trace the underlying cause.
