Heat pump repairs for Machynlleth homes
Aftercare matters as much as installation. For a heat pump in Machynlleth 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.
Repairs in Machynlleth that need a part ordered are explained and priced before the engineer leaves. Across Machynlleth and Powys, 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
- Heat pumps installed by another company that need a second opinion
- Systems losing pressure or needing frequent topping up
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- A clear explanation of the fault and a price for the repair before work goes ahead
- System refill, venting and recommissioning after the repair
- Reading of error history and operating data
- Supply and fitting of replacement parts
Outdoor units in exposed spots around Machynlleth can ice more heavily, so siting is checked as part of any icing fault.

Heat pump repairs in Machynlleth: questions
How much does a visit cost in Machynlleth?
The rate for a service or fault-finding visit is agreed before anyone attends. Any repair is priced in writing before parts are ordered, so you decide before work goes ahead.
Can you work on a heat pump in Machynlleth that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Machynlleth, 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.
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.
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.
