Inverter Technology
Our inverter system runs the compressor off of DC power to ensure unprecedented energy efficiency in both cooling and heating modes.

Intelligent Defrost
Did you ever get upset when the air conditioner stopped heating, when it entered the defrost cycle? This problem is prevented by our Flex series units. They start the defrost cycle when needed. More energy savings and more comfort for you!

Intelligent Pre-Heating
When turning on heating mode in winter, no air will blow until it has been sufficiently heated.
