Heat pump repairs for Aberystwyth homes
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.
For repeated faults in Aberystwyth, the engineer looks at the system design as well as the failed part. Across Aberystwyth and Dyfed, 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.
- Outdoor units that have become noisy, iced up or keep switching on and off
- Rooms or hot water not getting warm enough
- Systems losing pressure or needing frequent topping up
What's included
- System refill, venting and recommissioning after the repair
- Fault-finding visit at a rate agreed before attending
- Supply and fitting of replacement parts
- Testing of sensors, pumps, valves, pressures and electrics
- Refrigerant repairs by an F-gas certified engineer where needed
Repairs in Aberystwyth that need a part ordered are explained and priced before the engineer leaves.

Heat pump repairs in Aberystwyth: questions
Do you also cover Machynlleth?
Yes. We arrange heat pump servicing and repairs in Machynlleth, which is about 16 miles north-east of Aberystwyth, and across Dyfed.
How often should a heat pump in Aberystwyth 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 Aberystwyth that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Aberystwyth, 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.
How much does a heat pump repair cost?
Heat pump repairs have a typical range of £90–£1,100, including VAT, depending on the part and labour involved. Sensor replacements sit at the lower end, while control boards and refrigerant repairs on split systems sit higher. Every repair starts with a fault-finding visit, with a guide price of £90–£180 for the first hour, and the repair is priced before work goes ahead.
