How Does Unico Work?
Why Unico
Preferred Contractor

Get the comfort of central air and heating...without compromising the design of your classic or custom home.

Do you love your older home…except when the hot Chicago summers have you wishing for central A/C?

Do you want to add central heating and air to your classic home...but don’t want to sacrifice it’s vintage looks or gut the home for installation?

Are you planning a custom-built home and want to retain a clean profile without intrusive ductwork or soffits?

That’s all possible with the Unico System: a small duct, high-velocity HVAC system that’s ideal for older and custom-built homes. It can be discreetly retrofitted into classic homes or designed into new construction without the need for extensive remodeling or conventional ductwork.


How Does the Unico System Work?

Small duct, high velocity (SDHV) systems, like the Unico System, are designed to fit where conventional HVAC systems can’t. They add modern indoor comfort to homes that don’t have room for large ductwork, or where adding it would disrupt the home’s original design.

Instead of conventional ductwork, SDHV systems deliver conditioned air through flexible tubes fitted into existing wall cavities, ceilings or floors. Powerful modular air handlers circulate air through the home, yet are small enough to fit into ceilings, closets, crawl spaces or basements.



Why Choose the Unico System?

Due to its ability to fit into tight spaces, the Unico System is popular for:

  • Preservationists and owners for retrofitting older homes built before the advent of central heating and air conditioning
  • Designers and builders of custom and log/timber homes for including central air that doesn’t require alterations to the original plans
  • As a solution for providing standalone indoor comfort for room additions
Even though the Unico System is small, it delivers the same level of cooling as a conventional HVAC system three times its size.

The Unico System requires little to no remodeling to install (no soffits!), virtually eliminating build-out costs. There’s less mess, less installation time, and—most importantly—no need to gut your home for installation.

The Unico System’s supply tubing is designed for quietness as well as efficiency, with a nylon inner core and insulation that absorb sound. The air handlers isolate noise and vibration with closed cell, sound-deadening insulation. While you’ll feel the comfort of the cooled or heated air, you’ll hardly notice the system is running.

The Unico System draws the room air into its stream of cooled air by creating a gentle suction. This delivers even, draft-free cooling from room to room, floor to ceiling.

The temperature differential is no greater than 2 degrees throughout the home.

The Unico System removes up to 30% more humidity than conventional air conditioning and heating systems. So, you can keep your thermostat a few degrees higher to achieve the same level of comfort—and that saves on energy costs.
