Air Handling Units

Air Handling Units

Air Handling Units (AHUs) are essential components of HVAC (Heating, Ventilation, and Air Conditioning) systems, responsible for regulating and circulating air in large buildings or industrial spaces. These units consist of various components like fans, filters, coils, and dampers, working together to ensure optimal air quality and comfort. AHUs take in outside air, condition it by heating, cooling, or dehumidifying, and then distribute it throughout the space.

The efficiency of an AHU is crucial for maintaining a comfortable indoor environment, improving air quality, and reducing energy costs. Advanced AHUs come equipped with energy-saving features like variable speed fans and heat recovery systems, making them ideal for sustainable, environmentally-conscious operations. They also help maintain consistent temperature, humidity, and ventilation levels, which are vital for both human comfort and the protection of sensitive equipment.

Choosing the right AHU ensures optimal performance, longer lifespan, and reduced maintenance costs, making it an essential investment for commercial or industrial facilities.

Frequently Asked Questions (FAQ)

1. What is an Air Handling Unit (AHU)?

An AHU is a part of an HVAC system that circulates and conditions air by filtering, heating, cooling, and distributing it throughout a building.


2. What are the types of AHUs?

  • Packaged AHU – Pre-assembled with all components.

  • Modular AHU – Custom-built for specific applications.

  • Rooftop AHU – Installed on building rooftops for large-scale air handling.


3. How does an AHU improve energy efficiency?

  • Heat Recovery Systems reclaim waste heat from exhaust air.

  • Variable Speed Fans adjust airflow based on demand.

  • Smart Controls optimize temperature and humidity levels.


4. How often should an AHU be maintained?

  • Filters should be cleaned or replaced every 3–6 months.

  • Fans & Motors should be inspected every 6 months.

  • Coils & Ducts should be cleaned annually to prevent dust buildup.


5. Can an AHU be integrated with a Building Management System (BMS)?

Yes! Smart AHUs can be connected to BMS for remote monitoring and automation, improving efficiency and reducing operational costs.
