What to know about heat pump repairs in Stornoway
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.
Outdoor units in exposed spots around Stornoway can ice more heavily, so siting is checked as part of any icing fault. Repairs in Stornoway 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.
- Outdoor units that have become noisy, iced up or keep switching on and off
- Rooms or hot water not getting warm enough
- Heat pumps installed by another company that need a second opinion
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- Supply and fitting of replacement parts
- Testing of sensors, pumps, valves, pressures and electrics
- System refill, venting and recommissioning after the repair
- A clear explanation of the fault and a price for the repair before work goes ahead
For repeated faults in Stornoway, the engineer looks at the system design as well as the failed part.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland.

Heat pump repairs in Stornoway: questions
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.
How much does a visit cost in Stornoway?
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.
How often should a heat pump in Stornoway 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 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.
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.
