Why it Stands Out to Us

Besides having a noise level lower than 20dB and energy efficiency of 20 SEER, this unit is best known for improving the quality of indoor air to the maximum. The filter system comprised of multiple parts works to refresh the air circulating in the room.

Allergens, odors, bacteria, and viruses are reduced. You and your family can breathe easily. Another thing that makes this unit so great is the ductless installation. Not only does this make the installation process easier, but it also reduces heat loss significantly.

Bottom Line

In a nutshell, the system is highly energy efficient with a lot of benefits for the environment and the user too. The ductless system is also highly efficient as it minimizes heat loss.

Plus, the auto-clean feature does triple filtration, cleaning the air, and reducing the moisture. It is ideal for basement spaces because three-inch holes are needed for a conduit through the walls to hook up between outdoor and indoor units.


Installation is much easier, as no ductwork needs to be done

Zoning can be done with units by connecting mainly to one unit

Compact and flexible for cooling and heating of individual areas

No ductwork avoids energy loss related to the forced air systems

More flexibility is offered because indoor handlers are suspended from a ceiling, as well as mounted flush in the drop ceiling

Why it Stands Out to Us

The earth coupling option of this product marks its uniqueness among the rest of the competing brands. Earth is used by these geothermal systems as a heat sink and heat source. For the transferring of heat into or from the ground, ground loops (heat exchangers) are used after installation on the ground.

Plastic pipes of high-density polyethylene are used in it. Heat pumps and loops are connected after that. The fluid circulation starts in the loop piping. This transfers the heat between the earth and the pump.

Bottom Line

In a nutshell, this geothermal system has been distinguished for its outstanding features. The compact design and versatility help in the adaptability for replacing it. It is highly functional and has a compact design that is very stylish. It attracts the aesthetic sense of its users.

The design engineered for quiet operation reduces the noise levels. It is also remarkable for saving the money of its users because the two-stage compressors work in coordination with each other and with the temperature of the earth, which extends the service life. The advanced controls are another way of monitoring the equipment for longevity and reliability.
