An air handler, also known as an air handling unit (AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. Typically constructed as a large metal box, it contains components including:

• Blowers and fans for air circulation
• Heating or cooling elements (furnace or A/C components)
• Filter racks or chambers for air purification
• Sound attenuators for noise reduction
• Dampers for airflow control

AHUs typically connect to ductwork ventilation systems that distribute conditioned air throughout buildings while returning air to the unit. Some configurations exhaust air to the atmosphere and bring in fresh air, while others operate without ductwork for direct space conditioning.

Specialized Unit Types:

• Terminal Units: Compact local units with basic components (filter, coil, blower)
• Makeup Air Units (MAU): 100% outside air handlers with no recirculation
• Packaged Units (PU): Outdoor-rated units for rooftop installation
