Before you book: heat pump repairs in Glastonbury
Aftercare matters as much as installation. For a heat pump in Glastonbury 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.
Across Glastonbury and Somerset, refrigerant repairs on split systems are carried out by an F-gas certified engineer. Outdoor units in exposed spots around Glastonbury can ice more heavily, so siting is checked as part of any icing fault.
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 installed by another company that need a second opinion
- Outdoor units that have become noisy, iced up or keep switching on and off
- Systems losing pressure or needing frequent topping up
What's included
- Fault-finding visit at a rate agreed before attending
- 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
- Testing of sensors, pumps, valves, pressures and electrics
For repeated faults in Glastonbury, the engineer looks at the system design as well as the failed part.
Grants and rules for heat pumps in England
Homes in Glastonbury 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.

Inc VAT. The fault-finding rate is agreed before we attend; repairs are priced in writing before parts are ordered.
How long is the heating season in Glastonbury?
Glastonbury sees roughly 7 hours 53 minutes of daylight in late December against 16 hours 34 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.
What happens when you book in Glastonbury?
- Tell us the make if you know it, the error code or symptoms, and send photos of the unit and controller.
- We confirm the fault-finding rate and arrange a visit in Glastonbury.
- The engineer diagnoses the fault and gives you a written price for the repair.
- Parts are ordered once you agree, and the repair is completed and tested.
Heat pump repairs in Glastonbury: questions
How often should a heat pump in Glastonbury 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 Glastonbury that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Glastonbury, whoever fitted them. Tell us the make and model when you get in touch.
What should I check before booking a visit in Glastonbury?
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.
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.
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.
