What Is an Air Handler Unit?
An air handler unit is an indoor HVAC component that circulates and conditions air as part of a larger heating, ventilation, and air conditioning system. It usually includes a blower, filters, coils, dampers, and a casing. In many systems, it works with chillers, condensers, boilers, or outdoor units to deliver treated air to rooms through ductwork. visit at https://workmanservices.com.pk
The main job of an AHU is simple: move air, clean it, and help control temperature and humidity. That sounds basic, but in large buildings, this process is essential. Offices, hospitals, malls, hotels, factories, and commercial sites all depend on reliable air handling to maintain healthy and comfortable indoor conditions.

For many projects, the air handler unit is not a standalone machine. It is part of a wider HVAC network that must be matched to building size, usage pattern, occupancy, and indoor air quality goals.
