In industrial and large-scale commercial environments, proper air circulation, temperature control, and indoor air quality are essential—not just for comfort but for regulatory compliance and operational efficiency. Air Handling Units (AHUs) play a pivotal role in achieving these goals. At PlasTech Services Inc., we deliver expert AHU installation and mechanical services designed exclusively for heavy industrial, large-scale commercial, and government buildings.
If you’re responsible for facility management in manufacturing, data centers, distribution hubs, water treatment plants, or government facilities, understanding how AHUs support your environment is critical to maintaining uptime and performance.
What is an Air Handling Unit (AHU)?
An Air Handling Unit (AHU) is a centralized component of HVAC systems that regulates and circulates air through large buildings. Housed in a metal enclosure, it typically contains:
Blowers/fans
Heating/cooling coils
Filters
Dampers
Sound attenuators
Humidifiers/dehumidifiers
In an industrial setting, AHUs are engineered for high volume, efficiency, and durability—often operating continuously under harsh conditions.
Why Choose PlasTech Services for AHU Installations?
PlasTech Services Inc. is not your average HVAC contractor. We specialize in mechanical contracting services tailored for large-scale facilities only. That means no residential, no strip malls, and no small business offices.
Our AHU Services Include:
We collaborate directly with Mechanical, Electrical, and Plumbing (MEP) engineers to develop tailored AHU solutions for unique facility needs.
Our team can work with advanced 3D CAD tools to map and optimize AHU placements, duct paths, and structural impacts for a seamless integration.
We install only premium-grade AHUs with advanced filtration, noise reduction, and energy-efficient components.
All installations comply with ASHRAE, OSHA, and local code requirements to guarantee safe, code-compliant operation.
Applications We Serve
We work exclusively with facilities that demand large-scale mechanical expertise:
Manufacturing and production plants
Wastewater treatment and utility centers
Government buildings and municipal infrastructure
Higher education and research campuses
Data centers and critical environments
Industrial warehouse and distribution hubs
Modular AHUs - Adaptable units designed for customization in size and function.
Packaged AHUs - Factory-assembled systems that integrate seamlessly into existing infrastructure.
Custom-Built AHUs - For unique needs like chemical filtration, high-volume ventilation, or controlled environment cleanrooms.
Integration with Building Systems
AHUs don’t work in isolation. They’re the heartbeat of your facility’s HVAC system, integrating with:
Variable Frequency Drives (VFDs) for fan speed modulation
Building Automation Systems (BAS) for smart control
FCUs (Fan Coil Units) and RTUs (Rooftop Units) in zoned environments
Cost Considerations for Industrial AHUs
The cost of an industrial-grade AHU system can vary significantly depending on:
Unit size and capacity
Custom components or filters
Type of coils and motors used
Integration complexity
Control system requirements
At PlasTech, we help clients evaluate total lifecycle costs, not just initial installation. Long-term energy savings and reliability are key ROI drivers.
FAQ Section: Industrial AHUs
What is the AHU air handling unit?
An Air Handling Unit (AHU) is a large HVAC component responsible for regulating and circulating air within commercial or industrial buildings. It usually contains fans, heating/cooling coils, filters, and dampers.
What is the difference between AHU and HVAC rooms?
HVAC refers to the entire heating, ventilation, and air conditioning system, whereas an AHU is a single major component within that system. HVAC rooms often house AHUs and other mechanical equipment in large facilities.
What is the average cost of an AHU?
For industrial or large-scale commercial applications, AHU installation can range from $50,000 to $500,000 or more, depending on customizations, controls, and environmental demands.
What is the difference between AHU and FCU?
An AHU (Air Handling Unit) serves large areas or entire buildings and is typically installed in mechanical rooms or rooftops. A FCU (Fan Coil Unit) is a localized air handling device, usually used for individual rooms or small zones.
How do AHU and FCU work together?
AHUs condition the primary air, which is then distributed through ductwork. FCUs supplement air conditioning locally by adjusting temperature in individual spaces, often using the same chilled water or refrigerant lines.
Are AHU and RTU the same?
No. RTUs (Rooftop Units) are a type of packaged AHU installed on rooftops. RTUs are more common in commercial buildings, whereas AHUs may be installed inside large industrial plants or mechanical rooms.
What is the difference between an air handler and an air handling unit?
There is no functional difference. “Air handler” is shorthand for air handling unit (AHU).
Is AHU on every floor?
Not usually. Large AHUs serve multiple floors from central mechanical rooms or rooftops. However, multi-zone buildings may have smaller secondary AHUs or FCUs on separate floors.
Does AHU have a compressor?
Generally, no. AHUs do not contain compressors. Cooling is provided via chilled water supplied by a central chiller. Systems with compressors are typically RTUs or split systems.
What are the disadvantages of AHU?
Requires significant space
Higher upfront cost
Complex installation and duct routing
Regular maintenance needed for filters, fans, and coils
What is VFD in HVAC?
A Variable Frequency Drive (VFD) controls the speed of motors, such as those in AHU fans, improving energy efficiency by adjusting airflow based on demand.
How much does an AHU unit cost?
For industrial applications, pricing can range widely. A basic unit may start at $50,000, but fully integrated custom AHUs with advanced filtration and automation can cost several hundred thousand dollars.
Why Proper AHU Installation Matters
Poor installation of AHUs in industrial settings can lead to:
Uneven air distribution
System inefficiencies and energy waste
Equipment failure and downtime
Non-compliance with safety regulations
PlasTech’s expertise ensures every AHU is precisely sized, integrated, and commissioned for peak performance—backed by rigorous quality control protocols.
