Frequently Asked Questions


Where is The Unico System best suited and what are its benefits?

The Unico System can be used to cool or heat homes or buildings that have no ductwork, inadequate ductwork, or where little space for ducting is available. The Unico System adapts perfectly to any type of residential setting such as homes, condominiums, or apartments. It also adapts to many commercial and industrial applications. The Unico System operates like any other central air system, but with greater benefits.

With high velocity air, will the Unico System be noisy?

The Unico System is extremely quiet because of its special sound-absorbing insulation. We insulate our air handler and recommend using vibration pads on the system to reduce vibration and add extra sound absorption. Special sound-attenuated supply ducts ensure quiet operation. When properly installed in most cases, people don't even notice the system is running.

What sizes are available for the Unico System?

Currently, there are 1 to 5 tons of nominal cooling & heating.

What condensing unit must be used with The Unico System?

One of the best selling features of the Unico System is that it can be used with any condensing unit of proper capacity. There are hundreds of matches listed in the ARI Unitary Directory. More than likely, you can use the condensing unit you are most familiar with. We also recently launched a new type of outdoor unit - the iSeries. This unit is incredibly efficient and has many features and benefits over traditional condensing units.

How many BTUs are there per outlet?

Each outlet is capable of delivering up to 35 CFM (19 L/s) with a capacity of 1500 Btu/hr cooling and 3000 Btu/hr heating with hot water. We recommend that a minimum of 6 outlets per nominal ton be installed. However, this will vary depending on the design of your system and your load requirements.

What are the types of outlets, and where should they be placed?

There are two types of outlets currently available: the round supply outlet and the slotted outlet. Ideally, the outlets should be located in the ceiling 5-inches from the wall or corner. If conditions prohibit this, they can be placed in the floor or sidewall. Both round and slotted outlets come in a variety of colors and woods which can be stained to match a wood floor.

What types and sizes of ductwork are there?

The system requires only three types of duct - the main plenum which can be metal or fiberglass and the flexible supply tubing in aluminum and nylon cloth, which is 2" or 2.5" inside diameter supply duct with insulation.

How long can my main plenum and supply runs be?

The main plenum should be run as far as possible to keep supply runs as short as possible. The supply runs may be virtually as long as you need them to be. However, there will be reduced heating and cooling capacity in runs longer than 10 feet.

How does the Unico System provide return air?

The Unico System's return duct is like a conventional system. A single or multiple return system can be used, depending on the project needs. It can also provide 100% outside air when sized properly.

Can I heat as well as cool with The Unico System?

Yes, there are three ways to heat with our system:

Hydronic (hot water) coil
Heat pump with auxiliary
Electric duct heater
