Infinity® 17 Central Air Conditioner 24ANB7 Superior Efficiency, Comfort and Control Infinity series air conditioners are engineered to be our best units. Two-stage compression, high-efficiency and quiet operation are all key reasons why this unit deserves the Infinity series name. Two-stage compression lets the system bring the cool when it’s needed but allows it to function mostly in low-stage, where you get the highest efficiency and the best dehumidification due to longer run times. It’s also quieter in low stage. Pair it with an Infinity variable-speed indoor unit and an Infinity control for even smarter energy and comfort management and you’ve got an exceptional cooling system.
