Seamless HVAC Integration: How The Unico System Enhances Modular Home Design

This March 20, 2025 case study describes how Module used The Unico System, a small duct high velocity (SDHV) HVAC system, in modular homes for urban infill development in Pittsburgh, PA.

Key facts

• Author: Audree Grubesic.
• Read time: 2 min.
• Project: Black Street Development in the Garfield neighborhood of Pittsburgh, PA.
• Homes involved: three modular homes.
• Builder: Module, a manufacturer and builder of modular homes.
• System: The Unico System SDHV HVAC.

Why Module chose The Unico System

• Module needed an HVAC system that was energy efficient.
• The system had to fit into the home designs at the factory.
• It also had to connect and be commissioned onsite with ease.
• The Unico System was selected to meet those needs.

Factory integration

Module’s engineers worked with Unico’s modular design team to create a streamlined integration process. The article says the following components were incorporated during manufacturing:

• Modular air handling units
• Low-profile rectangular plenum, described as the main ducting
• Flexible supply tubing, described as room delivery ducting
• Unobtrusive bespoke outlets

Onsite support

Unico also helped connect the system elements, install and pipe the outdoor units, and commission the systems onsite.

Why the system fit modular homes

The article says Unico components take up far less physical space than traditional HVAC systems. That made them easier to incorporate into factory-built panels and modules. After delivery to the site, final connections and system startup were described as simple.

Outcome

• The Black Street Development was described as a resounding success.
• Module keeps one home as a show house.
• The other two homes sold quickly.
• The homes were described as affordable, energy-efficient, highly comfortable, and aesthetically beautiful.
