What to know about heat pump servicing in Dorchester
Aftercare matters as much as installation. For a heat pump in Dorchester 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 Dorchester include unvented cylinder safety checks alongside the heat pump itself. If a heat pump in Dorchester 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 pumps installed by another company that need a new servicing arrangement
- Homes where running costs have crept up or rooms feel cooler than before
- Landlords who need dated service records for each property
What's included
- Cleaning of the outdoor unit coil, fan area and condensate drain
- Expansion vessel, pressure relief and water quality checks
- A dated service record for your warranty and property files
- Unvented cylinder safety checks and legionella cycle check
- Glycol or antifreeze protection test where fitted
Heat pumps in Dorchester that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service.
Grants and rules for heat pumps in England

Heat pump servicing in Dorchester: questions
What should I check before booking a visit in Dorchester?
Note any error code on the controller, check the system pressure gauge if you have one, and make sure the outdoor unit is clear of leaves or snow. Photos of the unit and controller help.
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 Dorchester that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Dorchester, whoever fitted them. Tell us the make and model when you get in touch.
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.
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.
