The Unico System Is

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

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 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.

Ability to connect with the Unico System

One of the best features of the iSeries is the ability to be paired with the Unico System. Due to the multisplit capabilities of the outdoor inverter unit, you can have several zones of Unico throughout a home without the need for dampers. This also allows several air handlers to be connected to one outdoor unit with mini-splits at the same time for mixed applications. The possibilities are endless!

Outdoor Inverter Unit Features & Benefits

The iSeries outdoor inverter units, which utilize state-of-the-art inverter technology, are the heart of the iSeries line. These units range from one to four nominal tons and boast unsurpassed features and benefits.


Inverter Technology refers to the ability of the unit to modulate the power from 10% to 130% of the nominal value. Simply put, this means that the unit never goes through on/off cycles which are the times when traditional HVAC units use the most power. This also means that the unit will reach normal operating conditions much faster, which translates to reaching the indoor target temperature much quicker.


Because of the inverter technology, the iSeries units will be rated by AHRI up to 18-20 SEER. This means the units are incredibly energy efficient, saving you money.


You can connect one indoor unit to one outdoor unit, or several indoor units to one outdoor unit. This is a capability that can be achieved “out-of-the-box” without any additional modifications or special settings. This allows for incredible variety in configuring your HVAC system.


The outdoor units run at a sound level of just 40dB, which is no louder than the sound your refrigerator makes while running.


The iSeries outdoor units have been tested and successfully operated in extreme temperatures ranging from -35° up to 120°F, which speaks volumes to how robust these units are.


In cold weather, there are times when outdoor units may need to defrost due to ice buildup. Usually, this means a period of time where the indoor units blow cold air, but with iSeries, the revolutionary Cold Draft Prevention allows the outdoor units to defrost while the indoor unit continues to blow warm air, keeping you comfortable at all times.

iSeries Indoor High Wall Unit Features & Benefits

The iSeries ductless high wall units range from one to two tons and are quiet, compact, and discreet – everything you want from a high wall unit.


Installation of the indoor high wall units is made easy by the compact design and light weight – The larger of the two units measures just 9”Dx39”Lx11”H and weighs only 26 lbs.


The high wall units are exceptionally quiet at just 23dB while running. This is the equivalent of a soft whisper.


iSeries indoor high wall units come standard with a thermostat remote control, which can also be mounted to a wall like a standard thermostat. The remote can be programmed to control up to four different units at once, providing the ultimate control.
