About Air Handling Unit Service
Air handling unit (AHU) servicing in the UK — supply and extract fans, filter bank changes, heating and cooling coils, heat recovery, dampers and controls.
Our air handling unit service work in the UK is delivered by qualified commercial ventilation and HVAC engineers. Every visit is carried out to BESA SFG20 standards and ends with a detailed service report covering airflow static pressure, differential filter pressures, belt tension, motor operating currents, damper actuator travel, and heating/cooling coil temperature differentials.
We service supply, extract and heat-recovery AHU systems across offices, schools, kitchens, leisure centres and industrial facilities in the UK. Regular AHU filter replacements and coil cleaning protect indoor air quality (IAQ), ensure fire damper compliance, and prevent costly fan motor or drive failures.
Common AHU faults we fix include clogged panel/bag filter banks causing high differential pressure, snapped or loose fan belts, fan motor or bearing failure, seized motorized dampers, leaking LTHW/CHW or DX coils, heat recovery wheel drive faults, condensate pan blockages, and VFD/inverter error codes.
