Before you book: heat pump servicing in Hayes
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.
If a heat pump in Hayes has not been serviced for a while, the first visit includes a full check of settings and pressures. Landlords in Hayes can arrange servicing for several properties, with a dated record for each.
An annual service keeps a heat pump running efficiently, catches small faults early and is often a condition of the manufacturer's warranty.
- Systems where the manufacturer's warranty requires annual servicing
- Landlords who need dated service records for each property
- Heat pumps installed by another company that need a new servicing arrangement
What's included
- Controls and error log check, with settings adjusted where needed
- Expansion vessel, pressure relief and water quality checks
- Refrigerant circuit checks on split systems by an F-gas certified engineer
- A dated service record for your warranty and property files
- Unvented cylinder safety checks and legionella cycle check
Service visits in Hayes include unvented cylinder safety checks alongside the heat pump itself.

Heat pump servicing in Hayes: questions
How much does a visit cost in Hayes?
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.
Can you work on a heat pump in Hayes that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Hayes, whoever fitted them. Tell us the make and model when you get in touch.
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.
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.
