What to know about heat pump repairs in Cumbernauld
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.
Across Cumbernauld and Lanarkshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer. We repair heat pumps in Cumbernauld whoever installed them, including older monobloc and split systems.
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
- Heat pumps showing an error code or fault light
- Rooms or hot water not getting warm enough
What's included
- Testing of sensors, pumps, valves, pressures and electrics
- A clear explanation of the fault and a price for the repair before work goes ahead
- System refill, venting and recommissioning after the repair
- Fault-finding visit at a rate agreed before attending
- Reading of error history and operating data
Heat pump owners in Cumbernauld can arrange a fault-finding visit at a rate agreed before an engineer attends.

Heat pump repairs in Cumbernauld: 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 Cumbernauld?
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.
What should I check before booking a visit in Cumbernauld?
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 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.
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.
