Common Heat Pump Faults We Resolve Across Kent
Heat pumps are complex thermodynamic machines. When a problem arises, standard plumbers often lack the refrigeration and microprocessor knowledge required. Our engineers specialize strictly in heat pumps and climate systems.
settings_suggest Faults We Routinely Fix:
- verifiedRefrigerant leaks, low pressure errors, and electronic expansion valve (EEV) jamming.
- verifiedWater flow rate errors (7H error, A01, etc.) caused by blocked strainers, air locks, or failing circulating pumps.
- verifiedDefrost cycle failures where the outdoor coil becomes iced over and stops absorbing thermal energy.
- verifiedInverter PCB board communication dropouts and 3-way diverter valve hot water failures.
We provide transparent, fixed diagnostic pricing before commencing any work, so you are always in complete control.

Lifetime Local SupportFrequently Asked Questions
Everything you need to know about engineering standards, grants, and living with renewable systems in Kent.
help My heat pump is displaying an error code, what should I do?
Take a note of the fault code (e.g. 7H-01, U4, E03) and submit it via our online technical support form. Our engineers will review the diagnostics and provide immediate guidance.
help Why is my outdoor unit covered in thick ice?
Heat pumps routinely frost over and melt the ice via an automatic defrost cycle. However, if the unit remains a solid block of ice for hours, the defrost sensor or reversing valve may be faulty.
help Can you repair my heat pump if another company installed it?
Yes. A substantial portion of our repair work involves fixing or re-commissioning systems that were poorly installed by non-specialist contractors.
help Do you carry spare parts in your vans?
Our vans carry common universal components including sensors, circulating pumps, motorized valves, and filters. Brand-specific parts can typically be sourced within 24 hours.
