Heat Pump Servicing, Maintenance & Repairs
Fewer moving parts and long guarantees make heat pumps more cost-effective to service and maintain than traditional heating systems. Geo Green Power recommend an annual heat pump servicing for air-source heat pumps (ASHP) and ground-source heat pump (GSHP) systems to ensure that they run efficiently. Heat pump servicing and maintenance is rarely required outside of this annual health check and you can expect a well-maintained system to run effectively for at least 20 – 30 years.
Heat Pump Servicing
We recommend an annual service to ensure that your heat pump is running at its best and to maintain product warranties.
We offer service and maintenance for all our heat pump system installations and customers are automatically contacted 12 months after installation for their first annual check.
Our team is fully qualified to work on all renewable heating systems and we regularly undertake service and maintenance work on systems that we did not install.

Top Tips: Looking after your heat pump
Check for any leakages:
Although condensation is common, if you notice any considerable amounts of water or a clear leak then that indicates there is an issue somewhere with your pump.
Ensure your heat pump is receiving adequate airflow:
Heat pumps need their space! Ensure yours is in an area with plenty of breathing room and nothing covering it.
Clean & change filters:
The best way to ensure a long life for your heat pump is to keep it clean, as well as check and change the filters as needed.
Check for snow or ice:
During the winter, check your heat pump for any snow or ice build-up, as this can reduce the efficiency of your pump.
Verify thermostat sensors are working properly:
Keeping an eye on the temperature of your heat pump and ensuring the thermostat is accurate is a great way to look after your pump quickly and easily.
Heat pump problems and what to do
If your heat pump system is not working properly it will usually show a fault on your display. If this is a minor fault a reset should be able to fix the issue without any further action required. You should also check the heating pressure gauge, and if this is low use the filling loop to top the pressure up. Most systems require pressure to be set at 1.5 bar, but it is always best to check your Operations and Maintenance Manual.
If a fault appears regularly or you’re experiencing other issues with your heat pump, such as leaks, mechanical issues (such as a compressor or soft start failure), blocked filters, pressure alarm faults, or problems within the ground collector, such as air or lack of fluid, you will need an engineer to investigate and fix the problem. You should also contact an engineer if you are regularly being alerted to minor or recurring faults on the system display.
Heat Pump Repair for Breakdowns
Generally, repair and maintenance will be minimal for heat pumps as they have very few moving parts. Plus, Grade 1 manufacturers have a long life span so it is unlikely you’ll ever need a replacement.
However, if you think there is an issue, all repair work will have to be surveyed to identify which unit has become faulty; a system inspection will identify which units need replacing. We will quickly be able to quote for the required works and carry out these upon your request.
How do I know when my heat pump needs replacing?
Heat pump units typically have a longer lifespan than traditional boilers because they have fewer moving parts. With regular heat pump servicing and correct installation, a well-maintained system can last 25–30 years. Ongoing servicing plays an important role in monitoring system health, efficiency, and component wear, meaning potential end-of-life issues are often identified gradually rather than through sudden failure.
In most cases, you’ll know a heat pump is nearing replacement because it will start to experience more frequent faults or declining performance. These issues are usually highlighted during routine heat pump servicing, where engineers can assess whether repairs remain cost-effective. As systems age, they may also struggle to operate efficiently, leading to higher energy bills and reduced comfort levels, even if the system is still technically running.
You may need to consider replacing your heat pump if you notice one or more of the following signs:
- Repeated breakdowns or frequent callouts despite regular heat pump servicing
- Rising maintenance and repair costs that outweigh the value of the system
- Replacement parts becoming difficult or impossible to source for older models
- Reduced efficiency or noticeably higher energy bills
- Inconsistent heating or hot water performance
- The system has reached or exceeded its expected lifespan
If your heat pump is becoming increasingly expensive to maintain or can no longer be reliably repaired, replacement may be the most cost-effective long-term solution. Regular heat pump servicing ensures these decisions are informed, planned, and based on performance data rather than unexpected failure.
Does a heat pump need to be serviced?
Yes, a heat pump does need to be serviced to keep it running efficiently and reliably over its lifespan. Although heat pumps are lower maintenance than traditional heating systems, regular servicing helps maintain performance, reduce energy use, and prevent small issues from developing into costly faults. An annual service is typically recommended to protect warranties and ensure ongoing efficiency.
Heat pump servicing must be carried out by a qualified professional. In the UK, engineers should be MCS certified, and where refrigerants are involved, F-Gas certification is a legal requirement. These accreditations confirm the engineer is trained to service heat pumps safely and in line with industry and manufacturer standards.
Good installers also design systems with servicing in mind. This means ensuring easy access to components, fitting appropriate isolation points, and using quality equipment that supports long-term maintenance. A well-installed heat pump is not only more efficient but also simpler and more cost-effective to service over time.
How much does it cost to service a heat pump?
The cost of a heat pump service varies depending on the size and complexity of the system, but regular servicing is an essential part of keeping a heat pump efficient and reliable. As a guide, this depends on the size of your system. We service domestic systems from £249 + VAT. Annual heat pump maintenance helps protect warranties, maintain performance, and identify issues early, making it a cost-effective investment compared to unplanned repairs or reduced efficiency.
Why annual heat pump maintenance matters
A heat pump should be serviced annually to ensure it continues operating safely and efficiently. During a heat pump service, engineers will check refrigerant levels, electrical connections, airflow, controls, and overall system performance. However, if a heat pump has been installed poorly, servicing can become far more expensive. Incorrect system design, poor pipework, or limited access to components can lead to repeated faults, higher labour costs, and reduced system lifespan.
The impact of poor installation – and next steps
We have seen firsthand how poor installation can significantly increase long-term costs. For one customer in the Midlands, we were called in to assess a heat pump installed by another company that had ongoing performance and reliability issues. Due to incorrect installation and system design, the problems could not be resolved through standard heat pump maintenance, and the system ultimately had to be replaced entirely.
If you want peace of mind that your system is running efficiently and has been installed and maintained correctly, book a professional heat pump service with our accredited engineers today.
