Unico HVAC for modular manufacturing

The post describes The Unico System as a small-duct, high-velocity HVAC system for modular factories. It is designed to be installed in the factory, not pieced together on site.

Why factory installation matters

• Reduces field coordination.
• Limits inspection surprises.
• Simplifies GC closeout.
• May require only a licensed contractor for final connections.
• In some Colorado markets, manufacturers are selecting their own HVAC contractor.

Comfort and efficiency

• Even air distribution.
• Tighter control of temperature and humidity.
• Improved indoor air quality and comfort.
• Discreet outlets and small profiles that blend into ceilings or other finishes.

Space and routing advantages

The supply tubing is about 3 inches in diameter. The post says this allows routing between floors and helps avoid large chases. It can also reduce the need for equipment in unconditioned attics unless the design calls for conditioned space.

Case study

At a Boulder-area plant, Unico supported a manufacturer’s kickoff program. After early learnings, two installers completed a system in three days.

Humidity control

The system is presented as a fit for humid climates. The post says it targets meaningful moisture removal for healthier homes and better comfort in high-humidity regions.

Design and procurement support

• Dedicated design workflow for modular projects.
• Unico can run loads.
• Unico can select equipment.
• Unico can design the duct layout.
• Return packages can be delivered in PDF, AutoCAD, Revit, or 3D.
• WESCO partnership for stocked, kitted, and delivered components.
• Ancillary parts can be included.

Factory revenue opportunity

The post says factories can offer upgrades such as controls, thermostats, and ventilation packages. This creates an HVAC revenue path while improving the homeowner experience.

Manufacturer location

The Unico System designs and manufactures in Arnold, Missouri, with in-house testing.

Bottom line

The article argues that small-duct, high-velocity HVAC can reduce labor, support schedule predictability, and improve comfort in modular homes.
