Before you book: heat pump servicing in Farnham
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.
We service heat pumps in Farnham whoever installed them, including monobloc and split systems. If a heat pump in Farnham 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.
- Landlords who need dated service records for each property
- Systems where the manufacturer's warranty requires annual servicing
- Heat pumps installed by another company that need a new servicing arrangement
What's included
- Unvented cylinder safety checks and legionella cycle check
- Controls and error log check, with settings adjusted where needed
- Glycol or antifreeze protection test where fitted
- Refrigerant circuit checks on split systems by an F-gas certified engineer
- A dated service record for your warranty and property files
Service visits in Farnham include unvented cylinder safety checks alongside the heat pump itself.
Grants and rules for heat pumps in England
Homes in Farnham can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.

Designing for Farnham's winters
On the shortest day Farnham gets about 7 hours 52 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat pump servicing in Farnham: questions
Can you work on a heat pump in Farnham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Farnham, whoever fitted them. Tell us the make and model when you get in touch.
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 you also cover Aldershot?
Yes. We arrange heat pump servicing and repairs in Aldershot, which is about 3 miles north-east of Farnham, and across Surrey.
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.
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.
