Heat pump servicing for Llantwit Major homes
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.
Landlords in Llantwit Major can arrange servicing for several properties, with a dated record for each. Heat pumps in Llantwit Major that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service.
An annual service keeps a heat pump running efficiently, catches small faults early and is often a condition of the manufacturer's warranty.
- Homes where running costs have crept up or rooms feel cooler than before
- Heat pumps a year or more past installation
- Heat pumps installed by another company that need a new servicing arrangement
What's included
- Magnetic filter and strainer clean, with system pressure topped up
- Glycol or antifreeze protection test where fitted
- Cleaning of the outdoor unit coil, fan area and condensate drain
- Unvented cylinder safety checks and legionella cycle check
- A dated service record for your warranty and property files
Homes in Llantwit Major and across South Glamorgan can book servicing at a time of year that suits them, ideally before winter.

Heat pump servicing in Llantwit Major: questions
Do you also cover Cowbridge?
Yes. We arrange heat pump servicing and repairs in Cowbridge, which is about 4 miles north-east of Llantwit Major, and across South Glamorgan.
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.
Can you work on a heat pump in Llantwit Major that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Llantwit Major, whoever fitted them. Tell us the make and model when you get in touch.
Can you service a split system?
Yes. Split systems have refrigerant pipes running between the outdoor unit and an indoor unit, and checks on that refrigerant circuit must be done by an F-gas certified engineer. We arrange the service so a suitably certified engineer attends. The water side, controls and cylinder are checked in the same visit, just as on a monobloc system.
Is servicing needed to keep my warranty valid?
Often, yes. Many manufacturer warranties require an annual service with a dated record, and some extended warranties require an approved installer. Manufacturer warranties pass to you, and the length depends on the make and model. Check your warranty documents, and keep every service record safe with your MCS certificate and handover pack.
