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
- Reading of error history and operating data
- Refrigerant repairs by an F-gas certified engineer where needed
- System refill, venting and recommissioning after the repair
- A clear explanation of the fault and a price for the repair before work goes ahead
- Fault-finding visit at a rate agreed before attending
Outdoor units in exposed spots around Stewarton can ice more heavily, so siting is checked as part of any icing fault.
Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a Stewarton home, apply and receive the written offer before the installation date is fixed.

Heat pump repairs in Stewarton: questions
What should I check before booking a visit in Stewarton?
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.
How much does a visit cost in Stewarton?
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 Stewarton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Stewarton, whoever fitted them. Tell us the make and model when you get in touch.
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.
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.
