Frequently Asked Questions (FAQs)

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

An Air Handling Unit AHU regulates and circulates air as part of an HVAC system. It conditions air by filtering, heating, cooling, humidifying, or dehumidifying it before distributing it through ductwork into a building.

2. Who is the best AHU manufacturer in India?

Airtree is the best Ahu Manufacturer from Greater Noida India which provides Air handling unit all over india.

3. What is the average cost of an AHU system in India?

Costs vary widely based on capacity (CFM), features (like HEPA filtration, humidity control, or double-skin insulation), and customization. Small commercial units may start in the lakhs, while large industrial or pharma-grade AHUs can cost significantly more. It's best to request a quote based on your specific requirements.

4. What is the difference between an AHU and an HVAC system?

An AHU is a component within a larger HVAC (Heating, Ventilation, and Air Conditioning) system. The HVAC system is the complete setup — including chillers, ductwork, and controls — while the AHU specifically handles air filtration, conditioning, and distribution.

5. How often should an AHU be serviced?

Most AHUs require servicing every 3–6 months, though facilities with higher air quality demands (hospitals, pharma, cleanrooms) may need monthly or quarterly maintenance to ensure filters, coils, and fans are functioning optimally.

6. Can AHUs be customized for specific industries?

Yes. Manufacturers like Airtree offer customized AHUs for industries such as healthcare, pharmaceuticals, data centers, and manufacturing, where airflow, filtration level, and humidity control requirements differ significantly.

7. What are the different types of AHU systems available?

Common types include packaged AHUs, modular AHUs, Double skin AHUs, and rooftop AHUs. The right type depends on space constraints, capacity needs, and application (commercial vs. industrial vs. cleanroom).

8. Are energy-efficient AHUs worth the investment?

Yes. While energy-efficient AHUs may have a slightly higher upfront cost, they typically reduce electricity consumption significantly over the unit's lifetime, making them more cost-effective long-term — especially for facilities that run HVAC systems continuously.

9. How do I choose the right AHU capacity for my building?

AHU capacity depends on factors like the size of the space, occupancy, ventilation requirements, and heat load. A qualified HVAC consultant or manufacturer (like Airtree) can help calculate the right CFM (cubic feet per minute) rating for your specific building.
