Heat pump servicing in Dolgellau: what to expect
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.
Homes in Dolgellau and across Gwynedd can book servicing at a time of year that suits them, ideally before winter. Landlords in Dolgellau 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.
- Heat pumps a year or more past installation
- Systems where the manufacturer's warranty requires annual servicing
- Landlords who need dated service records for each property
What's included
- Cleaning of the outdoor unit coil, fan area and condensate drain
- A dated service record for your warranty and property files
- Unvented cylinder safety checks and legionella cycle check
- Expansion vessel, pressure relief and water quality checks
- Refrigerant circuit checks on split systems by an F-gas certified engineer
Heat pumps in Dolgellau that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service.

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.
