Understanding the Purpose and Function of an Air Handler Unit

In the realm of HVAC (Heating, Ventilation, and Air Conditioning), the Air Handler Unit (AHU) plays a pivotal role in ensuring the comfort and air quality of indoor environments. Often housed within large metal boxes, these units are the lungs of an HVAC system.

It’s responsible for the circulation and regulation of air within buildings. But what does an Air Handler Unit do? Why is it so crucial? This blog post delves into the primary purposes and functions of an AHU. Let’s shed light on its importance!

Circulation of Air

The primary function of an Air Handling Unit (AHU) is crucial in maintaining indoor air quality and comfort within a building. An AHU operates by drawing in fresh outside air. It then undergoes a conditioning process involving heating or cooling.

This is to reach the desired temperature and humidity levels. Following this, the conditioned air is distributed throughout the building. It provides occupants with a consistent and pleasant airflow. This continuous air circulation ensures a comfortable environment.

This also helps in regulating ventilation and air quality levels for the well-being of all within the space.


Another crucial function of the AHU is to filter the air that circulates through it. This process plays a pivotal role in eliminating various pollutants, allergens, and dust particles. It significantly enhances the overall indoor air quality.

By utilizing high-quality air filters, the system can efficiently capture even the tiniest particles. This can guarantee that the air circulated within the building is comfortable and also clean and safe for occupants to breathe in.

Humidity Control

Controlling the humidity level within a building is another critical function of an AHU. Excess humidity can lead to mold growth and a feeling of mugginess. Too little humidity can cause discomfort and health issues such as dry skin and respiratory problems.

The AHU works to maintain an optimal humidity level, contributing to the overall comfort and health of building occupants.

Integration with HVAC Components

The AHU functions as an integral part of the overall HVAC system. It works in tandem with other components such as:

  • cooling coils
  • heating elements
  • ductwork

This is to ensure a cohesive operation. The integration allows for the precise regulation of indoor climates. It adapts to the needs of the specific building and its occupants.

Companies like Zipf Air Inc. stands at the forefront of this technological evolution, driving innovation within the HVAC industry. With a focus on integrating AHU technology with other HVAC components, they can ensure a seamless and optimized climate control system.
