More on The Unico System


You’ve put your heart and soul into restoring your classic home. Or perhaps you and your architect are pushing boundaries, redefining style in creating your custom home. In either case, you don’t want installing central air conditioning and heating to compromise the perfect lines and spaces. Neither do we.

That’s why we created the Unico System, a high-efficiency cooling and heating system that can be discreetly retrofitted into vintage homes or designed into new construction without the need for extensive remodeling or intrusive ductwork. There’s less mess, less dust, less installation time—and no need to “gut” your home for installation.

Small is Huge

Unico plenum (main duct) is one-third the size of that of conventional systems and its flexible supply tubing (supply duct) 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 your home. Even though its footprint is small, the Unico System delivers the same level of cooling as a conventional system three times its size.

Whisper Quiet

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 decibels levels to the equivalent of a soft whisper. While you'll feel the comfort our system provides, you'll hardly notice it's running.

Draft-free, Even Temperatures

Traditional systems distribute air unevenly, dumping air into rooms, creating drafts and uneven temperatures throughout different parts of the room. The Unico System uses a principle called aspiration, creating a gentle suction around itself that draws the room air into its stream of cooled air. This delivers even, draft free cooling, from room to room, floor to floor, and floor to ceiling. The temperature differential is no greater than 2 degrees throughout your home.

Comfort by Design

The unique design of its cooling coil means 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 while feeling the same level of comfort—and that saves on energy costs.

Many Ways to Heat

The same benefits The Unico System provides for central cooling – unobtrusive, space-saving, energy efficient, superior comfort – can be experienced in a number of different central heating methods as well.

Whether you wish to use The Unico System as a sole, primary heat source or as a supplement to another heating method, you'll realize the same unparalleled comfort through a variety of possible configurations.

Unico hot water coil +

• Boiler
• Hot water heater
• Radiant system (radiators, baseboard, or in-floor)

The Unico System paired with a radiant heating system. When water is the heat source – via a boiler, hot water heater, etc. – this is known as "hydronic" heating.

Unico heat pump coil +

• Outdoor air-source heat pump unit
• Outdoor geothermal (ground-source) heat pump unit

This modern, glass-walled home is heated and cooled with Unico System heat pump coils. Note the innovative use of customized slotted outlets in the flooring.

Unico chilled water coil +

• Water-to-water geothermal heat pump
• Gas-fired outdoor chiller
• Air-cooled reverse cycle chiller

This mid-century modern ranch home in Texas is heated and cooled with a Unico chilled water coil paired with a gas-fired outdoor unit.

Unico Electric Duct Heater

The Unico System electric duct heater can be placed within the plenum (main duct system) for instant heat and is available in sizes ranging from 2 to 20 kW.

No matter which method you or your HVAC contractor choose, you'll be sure to get the very best in small-duct central heating with The Unico System.

Compatible with Major Outdoor Unit Brands

You may have noticed that we don't say much about outdoor units on this website. That's because The Unico System is compatible with virtually every major brand of outdoor unit available on the market.

The choice of outdoor unit is up to you, your installing contractor, and the type of installation you choose – heating and cooling with a heat pump coil, cooling only, heating only, etc.

Whichever application of outdoor unit you choose, because of our unique, tightly-sealed and virtually leak free ducts, you can be sure that you are actually getting the delivered efficiency listed on the outdoor unit. A higher SEER rating means nothing if 40% of the conditioned air leaks from the ducts – a problem you simply won't have with The Unico System.

So, talk with your installing contractor about the right choice of outdoor unit for your application. The choice is in your hands!
