Proprietary Process SiteBilt






Air Enterprises has been performing on-site assembly of custom air handling units for more than 40 years, and we leverage that experience into every project. Like our FactoryBilt® product, SiteBilt® air handling solutions are engineered for the highest level of quality and performance.

Many of our clients need to install their custom air handling units in tight spaces with limited access. This is easy and convenient with our SiteBilt® product.

How SiteBilt® works

SiteBilt® AHUs and ERVs make air handling unit installation simple in tight, “inaccessible” spaces and are ideal for replacement or retrofit applications. SiteBilt® can incorporate existing columns, beams and wind-bracing into the AHU design, our SiteBilt® process optimizes available mechanical space through on-site assembly. SiteBilt subassemblies are made of lightweight aluminum, allowing for easy transport through doorways, hallways and elevators for simplified installation.

Live Replacement
Air Enterprises can provide bridge units to support transitional replacement without interruption of service. Weekend retrofits of a building’s complete HVAC system is routine operation for our team. We replace live units with little to no downtime for non stop air handling.

Coordinated Site Installation Planning
Our construction method allows us to make units that fit a site and situation precisely. We make units that others cannot to fit the ideal circumstances of the site, not the reverse. Every Air Enterprises air handler is custom, designed for your optimal needs. Our project team takes onsite measurements, manages design to fit the available space and performs full project planning, logistics scheduling and execution. 

Benefits of using SiteBilt® include:

  • Simplified rigging and installation
  • Little-to-no building modification
  • Flexibility in design
  • Minimal disruption and downtime
  • Maximized mechanical space
