Before you book: heat pump servicing in Carmarthen
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.
Heat pumps in Carmarthen that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service. Landlords in Carmarthen can arrange servicing for several properties, with a dated record for each.
An annual service keeps a heat pump running efficiently, catches small faults early and is often a condition of the manufacturer's warranty.
- Heat pumps a year or more past installation
- Landlords who need dated service records for each property
- Systems where the manufacturer's warranty requires annual servicing
What's included
- Refrigerant circuit checks on split systems by an F-gas certified engineer
- Expansion vessel, pressure relief and water quality checks
- Magnetic filter and strainer clean, with system pressure topped up
- Cleaning of the outdoor unit coil, fan area and condensate drain
- Glycol or antifreeze protection test where fitted
Service visits in Carmarthen include unvented cylinder safety checks alongside the heat pump itself.

Heat pump servicing in Carmarthen: questions
Do you also cover Llanelli?
Yes. We arrange heat pump servicing and repairs in Llanelli, which is about 13 miles south-east of Carmarthen, and across Dyfed.
How often should a heat pump in Carmarthen be serviced?
Once a year is the usual recommendation, and many manufacturers make annual servicing a condition of the warranty. Check your warranty terms for the exact requirement.
What should I check before booking a visit in Carmarthen?
Note any error code on the controller, check the system pressure gauge if you have one, and make sure the outdoor unit is clear of leaves or snow. Photos of the unit and controller help.
Do I need to do anything between services?
A little. Keep the area around the outdoor unit clear of leaves, snow, plants and stored items so air flows freely. Check the system pressure gauge occasionally if you have one, and note any error codes. Avoid covering the unit or building an enclosure around it without advice, as this can reduce performance.
What does a heat pump service not include?
A service covers inspection, cleaning, testing and adjustment. It does not include replacement parts, major repairs, system flushing or radiator changes, which are quoted separately if needed. If the engineer finds a fault, they explain what it is, what it would cost to fix and whether it needs doing now or can wait.
