What to know about heat pump repairs in Hamilton
Whoever installed your heat pump, aftercare can be arranged in Hamilton. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Repairs in Hamilton that need a part ordered are explained and priced before the engineer leaves. For repeated faults in Hamilton, the engineer looks at the system design as well as the failed part.
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.
- Rooms or hot water not getting warm enough
- Heat pumps showing an error code or fault light
- Outdoor units that have become noisy, iced up or keep switching on and off
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- A clear explanation of the fault and a price for the repair before work goes ahead
- Supply and fitting of replacement parts
- Fault-finding visit at a rate agreed before attending
- System refill, venting and recommissioning after the repair
Heat pump owners in Hamilton can arrange a fault-finding visit at a rate agreed before an engineer attends.
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 Hamilton home, apply and receive the written offer before the installation date is fixed.

Heat pump repairs in Hamilton: 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.
Can you work on a heat pump in Hamilton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Hamilton, whoever fitted them. Tell us the make and model when you get in touch.
Do you also cover Motherwell?
Yes. We arrange heat pump servicing and repairs in Motherwell, which is about 2 miles north-east of Hamilton, and across Lanarkshire.
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.
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.
