What is the Unico System?

Small system, huge opportunity

Your customers have a lot of choices when it comes to indoor comfort products and the specialists who install them. Today's homeowners are armed with a wealth of online information about the features and benefits of various central air products and, likewise, they investigate the reputation and experience of HVAC contractors.

Technician installing Unico System supply tubing

Set yourself apart by offering your customers the best air conditioning system on the market, the Unico System.

The Unico System is small, a lot smaller than conventional systems. And that provides big advantages to HVAC installers. Whether you are adding air conditioning to existing homes, outfitting new custom homes, or simply replacing old systems, the Unico System fits where others can't.

Instead of conventional ductwork, flexible supply tubing is fitted into existing wall cavities, ceilings, or floors. Modular air handlers—small enough to fit into closets, attics, ceilings, crawl spaces, or basements—are powerful enough to effectively circulate air throughout any home. Even though its footprint is small, the Unico System delivers the same level of cooling as a conventional system three times its size.

Our supply tubing is designed to be as quiet and efficient as possible, with a nylon inner core and insulation that absorb sound. Our air handlers are designed to isolate noise and vibration, with closed cell, sound-deadening insulation. Together, they bring decibel levels to the equivalent of a soft whisper. While your customers will feel the comfort, they'll hardly notice it's running.

Small system, big customer comfort

Your customers will love the comfort available from the Unico System. Instead of the "dump and throw" method used by conventional and mini-split systems, Unico uses aspiration to deliver even, draft-free cooling. From room to room, floor to ceiling, and level to level, the temperature differential is never greater than 2 degrees throughout the home.

The Unico System cooling module uses a deep copper tube/aluminum fan coil that removes up to 30% more humidity than conventional systems. So, your customers can keep their thermostat a few degrees higher to achieve the same level of comfort—and save on energy costs to boot. For a look at our air handling unit performance, see our eBook on AHU Performance and Humidity Removal.

Traditional Home

Arts & Crafts Bungalow
Minneapolis, MN

Building a two-story addition on a traditional home poses many challenges, and for a Minneapolis couple, a primary goal was to seamlessly blend the new with the old, both outside and inside. They worked hard to select building materials that would honor the architectural integrity of their 1922 Arts & Crafts bungalow. But they faced a dilemma: how to add central air conditioning – with its boxy, intrusive ductwork – without ruining the charm of the home. more

Custom Home

The Woodland House
Kohler, WI

Dave and Jamie Van Dixhorn had a dream. Avid enthusiasts of modern architecture, the Van Dixhorns had longed to escape the urban rat race for years, and frequentlyfantasized about building the home of their dreams in the country. But as a busy developer in downtown Chicago, Dave's work delayed that dream for 15 years. However, three years ago the couple both took managerial positions at Kohler Company, maker of high-end plumbing fixtures, and had the opportunity to purchase land in the idyllic rural village of Kohler, WI. more

Commercial & Specialty

Spot Cooling a 3-Story Open-Air Driving Range
Seoul, Korea

The owners of a golf driving range in Korea were having a unique problem. Attendance dropped drastically during the hot summer months because guests were simply too uncomfortable to take their practice swings. Luckily, relief was available in the form of spot cooling from the makers of The Unico System. The longtime leader of small-duct central heating and cooling systems, The Unico System is known globally for its ability to provide superior comfort in homes and businesses where space is at a premium. An additional application for the system's flexible supply ducts is its ability to provide conditioned air to a specific location within a space without having to cool the entire space itself. more
