Renewable systems not performing? Not receiving your expected savings or tariff payments? Whether it’s your solar array or your air source heat pump, regular maintenance is vital. Pests like pigeons can damage solar wiring, while dirt and debris can clog heat pump filters and fans, drastically reducing efficiency.
Our personalised health checks ensure your tech stays running smoothly, preventing small glitches from becoming expensive repairs.
Is your Mitsubishi Ecodan showing an error code, or has your Daikin Altherma stopped generating heat entirely? Our certified engineers specialise in diagnosing control faults, compressor failures, and circulation issues to get your heating back online fast.
If your system is vibrating loudly or your electricity bills have spiked, your heat pump may be working harder than it needs to. We troubleshoot flow rates, re-balance radiators, and optimise your weather compensation curve to restore efficiency and quiet operation.
Most Air Source Heat Pump manufacturers require an annual service to keep your warranty valid. Our comprehensive health check inspects glycol levels, expansion vessels, and system pressure, giving you a full engineer’s report and peace of mind for the winter ahead.
A clogged evaporator coil can reduce your heat pump’s efficiency by up to 25%. We perform a safe, chemical-free deep clean of the external unit, removing leaves, moss, and debris to ensure maximum airflow and energy transfer.
In partnership with TGP, we have a UK-wide network of certified Heat Pump technicians who specialise in diagnostics and repair. We only work with the best local experts to get your system fixed quickly and efficiently.
Our experienced engineers have the expertise to diagnose and repair all types of solar panels, inverters, and battery systems, ensuring your specific equipment is performing as it should.
Note down the code displayed on your controller. You can try a system reset, but if the error returns, it indicates a specific fault (such as a flow restriction or sensor failure). Our engineers carry diagnostic tools for all major brands to identify and fix the issue.
Heat pumps run at lower flow temperatures (35-45°C) than gas boilers, so radiators will feel lukewarm rather than hot—this is normal. However, if your home isn’t reaching the target temperature, your weather compensation curve or flow settings likely need adjusting.
Manufacturers require an annual service to keep your warranty valid. Regular maintenance is also critical for maintaining high efficiency (COP); without it, your system has to work harder, using more electricity to produce the same amount of heat.
If your usage hasn’t changed but costs have risen, your heat pump may be running inefficiently. Common causes include a clogged heat exchanger, incorrect thermostat schedules, or the expensive backup immersion heater kicking in unnecessarily.
Light frost in cold weather is normal. Your system has an automatic ‘defrost cycle’ to melt this periodically. However, if the unit is encased in a block of solid ice that never clears, you likely have a sensor fault or a blocked condensate drain that needs clearing.
While a low hum from the fan is standard, loud rattling, grinding, or banging implies a mechanical issue. It could be loose casing, a failing fan bearing, or debris trapped inside the unit housing that needs removing.
Yes. This is often caused by a faulty diverter valve (which directs heat to the hot water tank) or a misaligned cylinder sensor. We can diagnose why your tank isn’t reheating effectively.
You should keep the immediate area clear of leaves, long grass, and snow. However, deep cleaning the delicate evaporator fins requires specialist chemicals and low-pressure cleaning to avoid damage. We include this in our service.
