What to know about heat pump servicing in Caerphilly
Aftercare matters as much as installation. For a heat pump in Caerphilly 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.
Service visits in Caerphilly include unvented cylinder safety checks alongside the heat pump itself. If a heat pump in Caerphilly has not been serviced for a while, the first visit includes a full check of settings and pressures.
An annual service keeps a heat pump running efficiently, catches small faults early and is often a condition of the manufacturer's warranty.

Heat pump servicing in Caerphilly: questions
How much does a visit cost in Caerphilly?
The rate for a service or fault-finding visit is agreed before anyone attends. Any repair is priced in writing before parts are ordered, so you decide before work goes ahead.
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.
Do you also cover Pontypridd?
Yes. We arrange heat pump servicing and repairs in Pontypridd, which is about 6 miles west of Caerphilly, and across Mid Glamorgan.
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.
