What to know about heat pump repairs in Stranraer
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.
Heat pump owners in Stranraer can arrange a fault-finding visit at a rate agreed before an engineer attends. Outdoor units in exposed spots around Stranraer can ice more heavily, so siting is checked as part of any icing fault.
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
- Rooms or hot water not getting warm enough

Heat pump repairs in Stranraer: questions
How often should a heat pump in Stranraer 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 Stranraer that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Stranraer, whoever fitted them. Tell us the make and model when you get in touch.
Do you also cover Newton Stewart?
Yes. We arrange heat pump servicing and repairs in Newton Stewart, which is about 22 miles east of Stranraer, and across Dumfries and Galloway.
Do refrigerant repairs need a specialist?
Yes. Any work on a heat pump's refrigerant circuit, such as tracing a leak, replacing a component or re-gassing, must by law be done by an F-gas certified engineer where the refrigerant is fluorinated, such as R32; units using R290 (propane) need an engineer trained in flammable refrigerants. On split systems the refrigerant runs through pipes inside your home, so leaks there are more likely than on sealed monobloc units.
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.
