Heat pump repairs in Conwy: what to expect
Aftercare matters as much as installation. For a heat pump in Conwy 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.
Heat pump owners in Conwy can arrange a fault-finding visit at a rate agreed before an engineer attends. Outdoor units in exposed spots around Conwy can ice more heavily, so siting is checked as part of any icing fault.
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
- Rooms or hot water not getting warm enough
- Systems losing pressure or needing frequent topping up
What's included
- Fault-finding visit at a rate agreed before attending
- Testing of sensors, pumps, valves, pressures and electrics
- Refrigerant repairs by an F-gas certified engineer where needed
- A clear explanation of the fault and a price for the repair before work goes ahead

We repair heat pumps in Conwy whoever installed them, including older monobloc and split systems.
