Inverter technology: Comfort without Compromise!

An INVERTER system automatically adjusts instantly for consistent comfort, whereas a conventional system constantly fluctuates, wasting energy and causing drafts. The money you save with this technology means more money each month for you and your family.

INVERTER Driven Technology is a sophisticated, electronic control system that detects any change in room or zone temperature. Like a car’s cruise control, it automatically adjusts the speed of the outdoor unit’s INVERTER-driven compressor for precise capacity and temperature control. Electronic LEVs exactly control refrigerant flow to regulate coil temperature.

Advanced Filtration System


Because there is no duct work, only small electrical and refrigerant lines, the installation of ductless heat pump systems is simple, quick, and cost effective, while being non-invasive to the structure and cosmetic style of your home.

Great for any space!
