Breaking HVAC Misconceptions in Offsite Construction: Wesco & Unico System, Lead the Way

On this episode of The Offsite Dirt Network, we sat down with two powerhouse partners in the offsite construction world: Kent Anderson of Wesco and Francis Leisure of Unico System, Inc. Both leaders have collaborated closely to bring forward practical, effective HVAC solutions for modular factories—solutions that boost efficiency, reduce cost, and ultimately support the growth of the offsite industry.

Together, they’re addressing one of the greatest challenges in offsite construction: helping manufacturers understand that HVAC can be successfully integrated directly in the factory—saving time, labor, and profit.

Misconception #1: “HVAC Can’t Be Installed in the Factory”

The Unico System can be installed in the factory with ease, and Kent highlights this as one of the biggest misconceptions in modular construction. Many people assume that HVAC systems, especially in multi-story modules or units with complex features like folding roofs, must wait until the building reaches the site.

But as Kent explains, that simply isn’t the case. “It’s the misconception that it can’t be done in the factory,” he said. “The Unico System absolutely provides the pathway to get this done.”

Because The Unico System is compact, flexible, and designed for tight spaces, it integrates seamlessly into the factory workflow. Manufacturers can complete the HVAC installation right on the production line, avoiding the typical coordination challenges of on-site work. This not only reduces labor and scheduling conflicts but also keeps projects moving efficiently from one stage to the next.

Misconception #2: “Factory-Installed HVAC Is More Expensive”

Francis weighs in on another widely held perception—that incorporating The Unico System in a modular setting must cost more.

“People think The Unico System will be more expensive, but that’s not accurate,” Francis explained. “There’s less material than traditional ductwork, less labor to install, and greater speed to completion.”

When manufacturers install HVAC in the factory, they reduce travel costs, eliminate repeat site visits, and keep control of their revenue in-house. These savings compound over the lifecycle of a project, making factory installation a financially smart decision.

Flexible System Placement for Any Design

One of the major advantages of The Unico System is its flexibility. Francis explains that the system can be integrated into several locations depending on the project’s design:

• Attic spaces

• Between floor joists

• Crawl spaces

• Or other custom placements based on architectural needs

  
  

The Unico System and Wesco review each project’s plans individually, ensuring the most efficient layout and installation strategy.

A Partnership That Eliminates Guesswork

Both partners emphasize that the relationship isn’t transactional—it’s long-term, supportive, and focused on enabling manufacturers to succeed.

Design Review & Load Calculations

The Unico System works directly with Wesco to evaluate modular manufacturers’ plans. They:

• Review architectural and mechanical layouts

• Provide system designs

• Run load calculations

• Deliver a full bill of materials and quote

This upfront work removes the stress and ambiguity for factory teams.

On-Site Training That Sets Manufacturers Up for Success

The Unico System also provides in-person training directly at the manufacturing plant so installation teams know exactly how to install the system correctly and consistently. This hands-on support shows crews how to integrate the equipment into their production line, how to route tubing and ductwork efficiently, and how to maintain quality from unit to unit.

“Onsite training in the factory really separates us,” Francis notes. “We want manufacturers to feel confident from day one.”

By working side by side with production teams, Unico trainers help establish repeatable processes that fit naturally into the plant’s workflow. They walk teams through best practices, troubleshoot real-time challenges, and ensure that every installer understands the full system, not just individual components. This approach builds long-term capability inside the factory and ensures that each module leaving the line has a properly installed, high-performing HVAC system.

Stock Availability & Just-In-Time Delivery

Wesco supports manufacturers by stocking material and delivering systems weekly—eliminating the need for plants to carry excessive inventory or wait for long lead times.

Looking Ahead: The Future of HVAC in Offsite Construction

Both Kent and Francis agree: this partnership is not short-term—it’s a long-range commitment designed to support the offsite industry for years to come.

By 2026 and beyond, they anticipate thousands of The Unico Systems moving through modular factories.

“This is the future of building,” Francis shared. “In five to ten years, offsite could become the largest segment of The Unico System.”

With rising support from federal partners, increasing demand for affordable housing, and the push for faster, more efficient construction methods, HVAC integration in modular factories will only continue to evolve.

Factory-installed HVAC isn’t just possible—it’s profitable, practical, and rapidly becoming the standard for leading modular manufacturers. With partners like Wesco Distribution and The Unico System paving the way, offsite construction continues to grow stronger, smarter, and more capable of meeting today’s urgent housing needs.

FAQs

1. Can HVAC systems truly be installed in all modular home designs?

Yes. The Unico system is highly adaptable and can be installed in various locations—attics, between floor joists, crawl spaces, or custom placements—based on the manufacturer’s plans.

2. Does factory installation cost more than traditional on-site HVAC work?

No. In fact, factory installation often costs less due to reduced labor, fewer materials, less coordination, and faster turnaround time. This approach also allows the factory to retain a larger portion of its revenue.

3. Do manufacturers receive support or training to install the Unico System?

Absolutely. The Unico System provides full training onsite at the manufacturing plant, ensuring teams understand how to properly install the system. Wesco also supports the process with stocked materials and regular delivery.
