Heat pump repairs in Tredegar: what to expect
Whoever installed your heat pump, aftercare can be arranged in Tredegar. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
For repeated faults in Tredegar, the engineer looks at the system design as well as the failed part. Across Tredegar and Gwent, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
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
- Outdoor units that have become noisy, iced up or keep switching on and off
- Rooms or hot water not getting warm enough
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- Fault-finding visit at a rate agreed before attending
- Testing of sensors, pumps, valves, pressures and electrics
- Supply and fitting of replacement parts
- Reading of error history and operating data
We repair heat pumps in Tredegar whoever installed them, including older monobloc and split systems.

Heat pump repairs in Tredegar: questions
Will the engineer need access indoors as well as outside?
Usually yes. The outdoor unit, the hot water cylinder, the controls and the pipework and valves indoors are all part of the visit, so allow access to each.
Can you work on a heat pump in Tredegar that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Tredegar, whoever fitted them. Tell us the make and model when you get in touch.
Do you also cover Ebbw Vale?
Yes. We arrange heat pump servicing and repairs in Ebbw Vale, which is about 2 miles east of Tredegar, and across Gwent.
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.
How much does a heat pump repair cost?
Heat pump repairs have a typical range of £90–£1,100, including VAT, depending on the part and labour involved. Sensor replacements sit at the lower end, while control boards and refrigerant repairs on split systems sit higher. Every repair starts with a fault-finding visit, with a guide price of £90–£180 for the first hour, and the repair is priced before work goes ahead.
