What to know about heat pump servicing in Devizes
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 Devizes that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service. If a heat pump in Devizes 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.
- 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

Heat pump servicing in Devizes: questions
How much does a visit cost in Devizes?
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.
How often should a heat pump in Devizes 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.
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 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.
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.
