We Repair More Than Just Heat Pumps
At Prestenergy, we don’t only repair heat pumps, we also diagnose and fix any related components connected to your central heating system or hot water cylinder. Whether your underfloor heating isn’t warming up, certain radiators aren’t heating properly, or your immersion heater has failed, our experienced engineers have you covered.
We take a whole-system approach, ensuring every part of your heating and hot water setup is working efficiently, reliably, and safely. No matter the issue, our team can identify the root cause and provide a fast, effective solution.
What to do when your heat pump needs a repair
1. Carry out basic checks (if safe to do so)
Where possible, check your heating system pressure and top it up if required. Inspect any system filters and, if you have an air source heat pump, look at the rear of the outdoor unit to ensure there are no leaves, debris, or blockages restricting airflow.
2. Take photos of any alarms or fault codes
If your system displays alarms or error codes, take clear photos. Capturing this information helps the engineer diagnose the issue more quickly and accurately.
3. Call for technical support
Prestenergy offers over-the-phone technical support to help get your system running again as quickly as possible. In many cases, we can resolve simple issues remotely, saving you time and reducing the need for callout fees.
4. Book regular servicing
Planned preventive maintenance is essential for a long-lasting, reliable heat pump system. An annual full service helps identify potential problems early, ensures efficient performance, and reduces the risk of unexpected breakdowns.
Heat Pump Servicing
Regular maintenance is essential to ensure the optimal performance and longevity of an air source and ground source heat pump. This includes checking and cleaning filters, inspecting the system for signs of wear and tear, and ensuring proper airflow. A yearly service should be carried out by a qualified engineer to ensure the system is operating efficiently and safely. Homeowners can also perform basic maintenance tasks, such as cleaning the outdoor unit and checking for debris. Regular heat pump maintenance can help prevent costly repairs and ensure the system continues to operate efficiently.

Detailed job specific heat loss, design and installation to the highest standards. Achieving optimal efficiency and ensuring the customer is left happy alongside a handover to improve their understanding of system controls and operation.
Underfloor Heating Maintenace
Often underfloor heating manifolds can get buried away and forgotten about. It is advised that they are maintained due to actuators failing, pins for individual zones being stuck and ensuring all zones achieve the correct flow rates for a healthy balanced system.
Offering one off servicing / maintenance visits or providing optional service plans to suit individual customer requirements. We ensure we provide the best professional service and leave the customer knowing their heat pump is in the best hands.
Heat Pump Refrigeration Work
Unfortunately heat pump components do fail, such as compressors, expansion valves, transducers / switches and leaks also occurring. Luckily we are trained (Fgas) to complete refrigerant repairs and get your system back up and running as quickly as possible.
Providing quick and efficient call outs to ensure any issues are resolved promptly, diagnosed correctly, with professional workmanship and going the extra mile to achieve great customer satisfaction.
Heating
All heating system requirements such as underfloor heating, radiators, system controls, checking water quality, system flushing. We have you covered and ensure the highest standards of workmanship.
Heat Pump Repair FAQs
Can a heat pump be repaired? A resounding yes. Most heat pump issues can be repaired. Moreover, timely repairs are essential to prevent further damage, restore efficiency, and avoid costly replacements. Common issues like dirty filters, debris, and refrigerant leaks can be fixed by a professional, who can also address more complex problems like compressor faults or electrical malfunctions.
What is the most common problem with heat pumps? Most common heat pump issues are caused by flow restrictions within the system. Blocked filters, low system pressure, or faulty valves are the most frequent culprits, and fortunately, these problems are usually straightforward and cost-effective to repair. Regular heat pump servicing and maintenance can prevent these issues from developing, ensuring the system continues to run efficiently and reliably.
Are heat pumps more expensive to repair? Heat pumps can sometimes have higher repair costs than traditional gas boilers, especially for complex faults or when the system is out of warranty but this can vary depending on system size and manufacturer. However, because heat pumps have fewer moving parts and use more efficient technology, they generally benefit from lower ongoing maintenance costs and fewer major component failures.
Why is my heat pump frozen or iced up? Air source heat pumps naturally gather frost in cold weather, but they should automatically defrost. If ice continues to build up, it may indicate a defrost cycle issue, blocked airflow, low refrigerant, or a faulty sensor. A professional inspection is recommended.
