Heat pump repairs for Thurso homes
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 Thurso can arrange a fault-finding visit at a rate agreed before an engineer attends. Across Thurso and the Highlands and Islands, 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 installed by another company that need a second opinion
- Outdoor units that have become noisy, iced up or keep switching on and off
- Heat pumps showing an error code or fault light
What's included
- Supply and fitting of replacement parts
- Fault-finding visit at a rate agreed before attending
- System refill, venting and recommissioning after the repair
- A clear explanation of the fault and a price for the repair before work goes ahead
- Reading of error history and operating data
Repairs in Thurso that need a part ordered are explained and priced before the engineer leaves.
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 Thurso home, apply and receive the written offer before the installation date is fixed.

Winter daylight and heating in Thurso
Thurso has about 6 hours 17 minutes of daylight at midwinter against 18 hours 22 minutes in midsummer. Heat pumps are designed to keep working well below freezing, but the design temperature for the survey is set for local conditions, not an average day.
How a visit works in Thurso
- Tell us the make if you know it, the error code or symptoms, and send photos of the unit and controller.
- We confirm the fault-finding rate and arrange a visit in Thurso.
- The engineer diagnoses the fault and gives you a written price for the repair.
- Parts are ordered once you agree, and the repair is completed and tested.
Thurso is in an area we cover by arrangement, so survey dates and any travel costs are confirmed individually in your quote.
Heat pump repairs in Thurso: 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.
What should I check before booking a visit in Thurso?
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.
Do you also cover Wick?
Yes. We arrange heat pump servicing and repairs in Wick, which is about 19 miles south-east of Thurso, and across the Highlands and Islands.
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.
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.
