Before you book: heat pump repairs in Abergavenny
A heat pump that is serviced and set up properly keeps running efficiently for many years. Many heat pump faults trace back to settings, low pressure or a worn part rather than the heat pump itself, and those can usually be put right.
Across Abergavenny and Gwent, refrigerant repairs on split systems are carried out by an F-gas certified engineer. We repair heat pumps in Abergavenny 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
- Heat pumps showing an error code or fault light
- Rooms or hot water not getting warm enough
What's included
- Reading of error history and operating data
- Fault-finding visit at a rate agreed before attending
- Supply and fitting of replacement parts
- Testing of sensors, pumps, valves, pressures and electrics
- A clear explanation of the fault and a price for the repair before work goes ahead
Outdoor units in exposed spots around Abergavenny can ice more heavily, so siting is checked as part of any icing fault.
Grants and rules for heat pumps in Wales
Homes in Abergavenny can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.

Heat pump repairs in Abergavenny: questions
Can you work on a heat pump in Abergavenny that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Abergavenny, whoever fitted them. Tell us the make and model when you get in touch.
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.
Do you also cover Crickhowell?
Yes. We arrange heat pump servicing and repairs in Crickhowell, which is about 6 miles north-west of Abergavenny, and across Gwent.
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.
Why does my heat pump keep switching on and off?
Frequent starting and stopping, called short cycling, is usually caused by an oversized heat pump, low water flow, too many zones closing at once or controls set with too narrow a range. It reduces efficiency and wears components. An engineer can check the settings, flow rates and design, and can often improve it with control changes before any parts are needed.
