FEATURES
Comfort and Convenience
Flexible and Quiet
Mini splits offer flexibility because they can 
be suspended from a ceiling, mounted flush
behind a drop ceiling, hung on a wall or floor-
standing. Ductless heat pumps allow for a
peaceful inside environment by enabling the
contractor to install components like 
compressors and motors outdoors.

Constant Comfort through 
Inverter Technology
Inverter technology is like cruise control for your 
heating or cooling system. Compressors only run as
fast as they need to handle the cooling or heating 
demand. They can handle greater extremes in 
temperature, are smoother and more stable in 
operation, and reach the desired temperature more
quickly than conventional air conditioners.
