Heat pump repairs in Cowbridge: what to expect
Aftercare matters as much as installation. For a heat pump in Cowbridge the visit checks the outdoor unit, the water circuit and the controls, and the engineer explains any settings that would help the system run more efficiently.
Outdoor units in exposed spots around Cowbridge can ice more heavily, so siting is checked as part of any icing fault. We repair heat pumps in Cowbridge whoever installed them, including older monobloc and split systems.
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.
- Outdoor units that have become noisy, iced up or keep switching on and off
- Rooms or hot water not getting warm enough
- Heat pumps showing an error code or fault light
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- Supply and fitting of replacement parts
- Reading of error history and operating data
- Testing of sensors, pumps, valves, pressures and electrics
- A clear explanation of the fault and a price for the repair before work goes ahead
For repeated faults in Cowbridge, the engineer looks at the system design as well as the failed part.
Grants and rules for heat pumps in Wales

Heat pump repairs in Cowbridge: questions
How much does a visit cost in Cowbridge?
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.
Can you work on a heat pump in Cowbridge that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Cowbridge, whoever fitted them. Tell us the make and model when you get in touch.
Do you also cover Llantwit Major?
Yes. We arrange heat pump servicing and repairs in Llantwit Major, which is about 4 miles south-west of Cowbridge, and across South Glamorgan.
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.
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.
