A heat pump service is an annual inspection and maintenance visit that checks the outdoor unit, the heating water circuit, the controls and the hot water cylinder are working safely and efficiently. Heat pumps have no burner or flue to inspect, but they rely on clean water flow, correct pressures and well-set controls, all of which can drift over a year.
Heat pumps in Powys that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service. Homes in Powys and across Powys can book servicing at a time of year that suits them, ideally before winter. Landlords in Powys can arrange servicing for several properties, with a dated record for each.
Who it suits
- Heat pumps a year or more past installation
- Systems where the manufacturer's warranty requires annual servicing
- Heat pumps installed by another company that need a new servicing arrangement
- Landlords who need dated service records for each property

Heat pump servicing questions
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.
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.
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.
