Before you book: heat pump repairs in Dumfries
Whoever installed your heat pump, aftercare can be arranged in Dumfries. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
For repeated faults in Dumfries, the engineer looks at the system design as well as the failed part. Repairs in Dumfries that need a part ordered are explained and priced before the engineer leaves.
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.
- Systems losing pressure or needing frequent topping up
- Heat pumps showing an error code or fault light
- Rooms or hot water not getting warm enough
What's included
- Supply and fitting of replacement parts
- A clear explanation of the fault and a price for the repair before work goes ahead
- Testing of sensors, pumps, valves, pressures and electrics
- Reading of error history and operating data
- Fault-finding visit at a rate agreed before attending
Outdoor units in exposed spots around Dumfries can ice more heavily, so siting is checked as part of any icing fault.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Dumfries can apply to Home Energy Scotland for a grant of up to £7,500 towards a heat pump, with up to £1,500 more for eligible rural and island homes, plus an optional interest-free loan of up to £7,500. You need a written funding offer before any work starts.

Heat pump repairs in Dumfries: questions
How much does a visit cost in Dumfries?
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.
What should I check before booking a visit in Dumfries?
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.
Can you work on a heat pump in Dumfries that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Dumfries, 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.
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.
