Heat pump repairs for Llangollen homes
Whoever installed your heat pump, aftercare can be arranged in Llangollen. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Across Llangollen and Clwyd, refrigerant repairs on split systems are carried out by an F-gas certified engineer. Repairs in Llangollen 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
- Outdoor units that have become noisy, iced up or keep switching on and off
- Systems losing pressure or needing frequent topping up
What's included
- Supply and fitting of replacement parts
- Reading of error history and operating data
- Testing of sensors, pumps, valves, pressures and electrics
- Refrigerant repairs by an F-gas certified engineer where needed
- Fault-finding visit at a rate agreed before attending
Outdoor units in exposed spots around Llangollen can ice more heavily, so siting is checked as part of any icing fault.
