Heat pump servicing in Llanelli: what to expect
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.
We service heat pumps in Llanelli whoever installed them, including monobloc and split systems. Service visits in Llanelli include unvented cylinder safety checks alongside the heat pump itself.
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 installed by another company that need a new servicing arrangement
- Landlords who need dated service records for each property
- Heat pumps a year or more past installation
What's included
- Cleaning of the outdoor unit coil, fan area and condensate drain
- Expansion vessel, pressure relief and water quality checks
- Magnetic filter and strainer clean, with system pressure topped up
- Glycol or antifreeze protection test where fitted
- Unvented cylinder safety checks and legionella cycle check
Heat pumps in Llanelli that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service.

Designing for Llanelli's winters

Heat pump servicing in Llanelli: questions
What should I check before booking a visit in Llanelli?
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.
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.
How often should a heat pump in Llanelli 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.
How much does a heat pump service cost?
An annual heat pump service has a guide price of £120–£250, including VAT. Where your price sits depends on the type of system, whether it is a split system needing refrigerant checks and whether an unvented cylinder is included. Any parts or repairs found during the service are explained and priced before any work goes ahead.
How often should a heat pump be serviced?
Once a year is the usual recommendation for air source heat pumps, and many manufacturers require it as a warranty condition. An annual visit cleans filters and strainers, checks pressures and controls, and tests the unvented cylinder's safety devices. If you notice a drop in performance, unusual noises or repeated error codes between services, arrange a visit sooner.
