Availability confirmed from postcode and system details
Fault diagnosis based on the manufacturer, model, error codes and system history Checks of electrical supply, controls, sensors, pumps, valves and refrigerant-side indicators by appropriately qualified personnel Investigation of reduced heating or hot-water performance, unusual noise, leaks or repeated shutdowns Repair or replacement recommendations that distinguish between the heat-pump unit, emitters, controls and wider heating system Safe isolation and escalation where electrical, refrigerant or water-system risks are identified

Use your postcode, system details and requested support to confirm the appropriate availability and appointment route.
A repair or diagnostic visit is shaped around the reported fault and the system behaviour that can be assessed.
Use the booking form to provide your postcode and choose the support you need. That information is used to confirm the right next step.
These public sources inform the guide. They do not establish service availability or describe work by Heat Pumps Service.
The useful starting information is the Carmarthen postcode, heat-pump type, make and model, fault or error codes, symptoms, service history and whether heating, hot water or both are affected. Photographs of the controller and visible installation may also help, provided they do not involve unsafe access or opening equipment.
Yes. Carmarthenshire’s Local Area Energy Plan identifies insulation and appropriate ventilation as ways to reduce energy demand and make buildings easier and cheaper to heat. They are therefore relevant context for assessing system performance, alongside emitters, controls and the heat pump itself.
