Before you book: heat pump repairs in Aberdare
Aftercare matters as much as installation. For a heat pump in Aberdare 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.
For repeated faults in Aberdare, the engineer looks at the system design as well as the failed part. Heat pump owners in Aberdare 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.
- Heat pumps showing an error code or fault light
- Outdoor units that have become noisy, iced up or keep switching on and off
- Heat pumps installed by another company that need a second opinion
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- Testing of sensors, pumps, valves, pressures and electrics
- Reading of error history and operating data
- 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
Outdoor units in exposed spots around Aberdare can ice more heavily, so siting is checked as part of any icing fault.

Heat pump repairs in Aberdare: questions
How often should a heat pump in Aberdare 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.
Do you also cover Mountain Ash?
Yes. We arrange heat pump servicing and repairs in Mountain Ash, which is about 4 miles south-east of Aberdare, and across Mid Glamorgan.
Can you work on a heat pump in Aberdare that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Aberdare, whoever fitted them. Tell us the make and model when you get in touch.
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.
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.
