Before you book: heat pump repairs in Farnborough
Whoever installed your heat pump, aftercare can be arranged in Farnborough. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Outdoor units in exposed spots around Farnborough can ice more heavily, so siting is checked as part of any icing fault. Across Farnborough and Hampshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
When a heat pump shows an error, loses pressure or stops heating, an engineer diagnoses the cause and explains the repair and its cost before fixing it.
- Heat pumps showing an error code or fault light
- Systems losing pressure or needing frequent topping up
- Rooms or hot water not getting warm enough
What's included
- Testing of sensors, pumps, valves, pressures and electrics
- Supply and fitting of replacement parts
- Fault-finding visit at a rate agreed before attending
- A clear explanation of the fault and a price for the repair before work goes ahead
- Reading of error history and operating data
Heat pump owners in Farnborough can arrange a fault-finding visit at a rate agreed before an engineer attends.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Farnborough quote.

Farnborough sees roughly 7 hours 52 minutes of daylight in late December against 16 hours 36 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Heat pump repairs in Farnborough: questions
How often should a heat pump in Farnborough 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.
Can you work on a heat pump in Farnborough that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Farnborough, 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.
Why is my heat pump showing an error code?
An error code is the heat pump's way of reporting a problem it has detected, such as low water flow, a sensor reading out of range or a communication fault between units. Note the code and check the manual, as some codes clear after a simple reset or pressure top-up. If it returns, an engineer can trace the underlying cause.
Can you repair a heat pump installed by another company?
Yes. We carry out fault-finding and repairs on heat pumps installed by other companies, including monobloc and split systems. Tell us the make, model and approximate age when you get in touch, plus any error code shown. If the system is still under the manufacturer's warranty, it may be quicker to contact the original installer or manufacturer first.
