What to know about heat pump repairs in Andover
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.
Repairs in Andover that need a part ordered are explained and priced before the engineer leaves. Heat pump owners in Andover can arrange a fault-finding visit at a rate agreed before an engineer attends.
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.
- Outdoor units that have become noisy, iced up or keep switching on and off
- Heat pumps showing an error code or fault light
- Systems losing pressure or needing frequent topping up
What's included
- Testing of sensors, pumps, valves, pressures and electrics
- Supply and fitting of replacement parts
- A clear explanation of the fault and a price for the repair before work goes ahead
- Reading of error history and operating data
- Fault-finding visit at a rate agreed before attending
For repeated faults in Andover, the engineer looks at the system design as well as the failed part.
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 Andover quote.

Short winter days in Andover and what they mean
On the shortest day Andover 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.

- We confirm the fault-finding rate and arrange a visit in Andover.
- The engineer diagnoses the fault and gives you a written price for the repair.

Heat pump repairs in Andover: questions
Do you also cover Winchester?
Yes. We arrange heat pump servicing and repairs in Winchester, which is about 13 miles south-east of Andover, and across Hampshire.
How often should a heat pump in Andover 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 Andover that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Andover, whoever fitted them. Tell us the make and model when you get in touch.
Is ice on my heat pump a fault?
Some frost on the outdoor unit in cold, damp weather is normal, and the unit clears it with regular defrost cycles, often releasing a little vapour. It becomes a fault when thick ice builds up and does not clear, or when ice blocks the fan. That can point to poor airflow, a failed sensor, drainage problems or low refrigerant, and needs checking.
Why does my heat pump keep switching on and off?
Frequent starting and stopping, called short cycling, is usually caused by an oversized heat pump, low water flow, too many zones closing at once or controls set with too narrow a range. It reduces efficiency and wears components. An engineer can check the settings, flow rates and design, and can often improve it with control changes before any parts are needed.
