Main point

The post says HVAC can be integrated directly in the factory for modular construction. The goal is to save time, labor, and cost while supporting offsite manufacturing.

Misconception 1: HVAC cannot be installed in the factory

The post says this is false. The Unico System is described as compact, flexible, and suitable for tight spaces, including multi-story modules and units with folding roofs.

Factory installation is presented as a way to avoid on-site coordination problems and keep projects moving through the production line.

Misconception 2: Factory-installed HVAC costs more

The post says factory installation is not more expensive. It cites less material than traditional ductwork, less labor, and faster completion.

It also says manufacturers can reduce travel costs, avoid repeat site visits, and keep more revenue in-house.

How Wesco and Unico support manufacturers

Training and factory support

The Unico System provides in-person training at the plant. The training covers installation methods, tubing and duct routing, and quality control from unit to unit.

Wesco supports plants with stocked material and just-in-time delivery so factories do not need to carry excessive inventory.

Future outlook

The post says the partnership is long-term. It states that by 2026 and beyond, thousands of Unico systems are expected to move through modular factories.

Francis Leisure says offsite construction could become the largest segment of The Unico System in five to ten years.

FAQs

Can HVAC systems be installed in all modular home designs?

Yes. The post says The Unico System can be installed in attics, between floor joists, crawl spaces, or custom locations based on the plans.

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

No. The post says it often costs less because of reduced labor, fewer materials, less coordination, and faster turnaround.

Do manufacturers receive support or training?

Yes. The post says Unico provides onsite training, and Wesco supports the process with stocked materials and regular delivery.
