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.

What People Ask About Air Handling Unit Service
What does an Air Handling Unit (AHU) service involve?
An AHU service includes checking and maintaining components such as supply and extract fans, filter bank changes, heating and cooling coils, heat recovery mechanisms, dampers, and controls. This ensures your unit operates efficiently and reliably for mission-critical cooling. Our F-Gas certified engineers perform this work.
What does AHU stand for?
AHU stands for Air Handling Unit. These units are integral components of HVAC systems, used to regulate and circulate air as part of a building's heating, ventilating, and air conditioning system. They condition and distribute air through ductwork. We service all types of AHUs.
Is an AHU the same as air conditioning?
While an AHU is a key component of an air conditioning system, it is not the same as air conditioning itself. An AHU handles and circulates air, often integrating heating, cooling, and filtration, as part of a larger HVAC system. Our F-Gas certified engineers are experts in AHU maintenance.
How much does Air Handling Unit servicing cost?
AHU servicing starts from £195 per unit. We provide fixed written quotes with no call-out fee, ensuring transparent pricing. For sites with multiple AHUs, customised Planned Preventative Maintenance (PPM) contracts are available to suit your specific needs and budget.
