The Freus is the most energy efficient unitary air conditioner on the market, reducing air conditioning costs by 40 to 60 percent versus standard equipment, saving hundreds of dollars a year. The Freus is also designed for low maintenance, with a fiberglass cabinet, triple thickness coils protected from salt air, and high pressures in the compressor only half the level of an air-cooled unit. Unlike other high efficiency condensing units, Freus has no expensive electronics on board to corrode, short or get surged by lighting. All these features mean longer life with lower maintenance. In addition, the steady efficiency performance of the Freus at high and low outdoor temperatures creates more even cycle times, providing for better household dehumidification in humid climates.
