The ducted options can be used on a multi system combined with ductless, as standalone or to replace traditional ducted systems. They come in a traditional air handler or slim design. The slim design is only 12 inches tall which makes it an option for low attic access designs.
These systems can be used to replace your traditional system often at a much lower cost than other high efficiency options while providing you with the same warranty. Some have their own specialized controls and some will work with the traditional thermostat that you have always used. They can be used from server rooms, to modular homes, to full homes.
We feel that this is the future of ducted air conditioning as several high efficiency options are available at a value price.
