Heat Pump Repair & Servicing in Newbury, Berkshire

Whether your heat pump has stopped working, isn’t performing as efficiently as it should, or is simply due its annual service, TJR Heating & Cooling provides expert heat pump repair and servicing across Newbury and the wider region. As Heat Geek certified engineers, we diagnose faults accurately, carry out repairs that last, and keep heat pumps running at their best year after year.

Heat Pump Repair & Maintenance Across Newbury & Beyond

Heat pumps are sophisticated pieces of equipment, and when something isn’t right, you need an engineer who genuinely understands how they work. At TJR, heat pumps are our core specialism. We understand the refrigeration cycle, the controls, the flow temperature settings, and the ways in which a system can gradually drift from optimal performance without triggering an obvious fault code.

Whether it’s a straightforward repair or a more complex diagnostic job, we approach every callout the same way: find the root cause, explain it clearly, and fix it properly. We work on systems we’ve installed ourselves and on systems installed by others, across Berkshire, Hampshire, Oxfordshire, and Witlshire.

Heat Pump Servicing

Why Annual Servicing Matters

A heat pump that isn’t regularly serviced will gradually become less efficient, use more electricity to deliver the same level of heat, and become increasingly vulnerable to component failures. Most manufacturer warranties also require annual servicing to remain valid – so skipping it can be a costly decision in more ways than one.

An annual service from TJR keeps your system running at peak efficiency, catches developing issues before they become failures, and gives you confidence that your heat pump will perform reliably when you need it most – particularly through the colder months when it’s working hardest.

What’s Included in Our Heat Pump Service

Our heat pump service is thorough and methodical – we take the time to assess how the system is actually performing and make adjustments where needed. A typical service with TJR includes:

Written service report covering everything checked, anything found, and honest recommendations on anything that needs attention
Full system inspection of both indoor and outdoor units, including pipework, electrical connections, and refrigerant line insulation
Refrigerant level check for leaks and correct levels, carried out in full F-Gas compliance as REFCOM registered engineers
Coil and filter cleaning to restore airflow and prevent unnecessary wear on components
Electrical and controls check, including flow temperature settings and heating curves to ensure the system is configured for maximum efficiency
Performance testing across all operating modes, measuring actual output against expected performance
Defrost cycle check to confirm the system is set up for reliable winter operation

Common Heat Pump Problems We Fix

Heat pumps can develop a range of issues over time, some of which present as obvious faults and others which show up more subtly as reduced efficiency or unexplained increases in running costs. Common problems we diagnose and repair include:

Reduced heat output – if the system is running but the property isn’t reaching temperature, the cause could be anything from a refrigerant issue to incorrect flow temperature settings or a problem with the distribution system
Unusual noises – rattling, grinding, or clicking from either unit usually indicates a mechanical issue that’s worth catching early before it becomes a more involved repair
The system cutting out or failing to start – repeated shutdowns or failure to start can point to sensor faults, electrical issues, refrigerant problems, or control system errors, which we identify using dedicated diagnostic equipment
Ice buildup on the outdoor unit – some frost is normal, but persistent or heavy ice usually points to a defrost cycle, airflow, or refrigerant issue that needs investigating
Rising energy bills without a clear cause – often the result of a gradual issue such as dirty coils, dropping refrigerant levels, or drifting flow temperatures rather than a sudden failure
Error codes and warning lights – we’re familiar with the diagnostic systems used by all major manufacturers and can interpret and act on fault codes quickly and accurately

Why Heat Pump Repairs Need a Specialist

Heat pumps are fundamentally different from gas boilers, and the skills required to diagnose and repair them reflect that. They involve refrigeration circuits, electrical control systems, and flow temperature management that a general heating engineer won’t necessarily have the knowledge or equipment to deal with properly.

As Heat Geek certified engineers and REFCOM registered technicians, we have both the technical training and the diagnostic tools to work on heat pump systems properly. We’re familiar with systems from Vaillant, Mitsubishi, Daikin, Samsung, and other leading manufacturers, and we approach every repair with the same methodical, root-cause focus that we bring to our installations.

“I thoroughly recommend Tim; his knowledge of the ASHP system appeared to far exceed that of other specialists that I have used before, and I look forward to checking in with him for annual servicing and any other advice and guidance that we might need. Tim was approachable and willing to take the time to speak with us throughout the process to make sure that we made an informed decision in relation to what was an expensive repair/refit.

FAQs

How often should a heat pump be serviced?

Most manufacturers recommend an annual service to keep the system running efficiently and to maintain warranty cover. We’d suggest booking a service toward the end of summer so the system is checked and optimised before the heating season begins and it’s working at full load.

Do you service heat pumps you haven’t installed?

Yes. We carry out servicing and repairs on heat pump systems regardless of who installed them or which manufacturer supplied them. If you’re not sure whether your system falls within our coverage, just get in touch and we’ll let you know.

Can you repair heat pumps that are still under manufacturer warranty?

It depends on the warranty terms and the nature of the fault. We can advise you on whether a repair should be handled under warranty and help you navigate the process with the manufacturer if so. For Vaillant systems, as an approved installer we can carry out warranty work directly.

What brands of heat pump do you work on?

We work on heat pump systems from all major manufacturers, including Vaillant, Mitsubishi, Daikin, Samsung, Panasonic, and others. If you’re unsure whether we cover your system, just ask.

Is there anything I can do to keep my heat pump running efficiently between services?

Yes – keeping the area around the outdoor unit clear of debris, leaves, and vegetation is the most important thing you can do. Checking that your filters are clean, making sure the system controls are set correctly for the season, and not making large manual adjustments to flow temperatures also helps. We’re happy to advise on best practice for your specific system at the end of a service visit.
