Frigidaire's 12,000-BTU 115V casement/slider room air conditioner is the perfect solution for cooling rooms with casement windows and horizontal sliding windows up to 640 square feet. This unit is specifically designed for use with casement windows or sliding windows and is not suitable for standard (double-hung) window installation. Ready-select electronic controls allow you to easily select options with the touch of a button. The full-function remote control allows you to precisely control the temperature and fan speed from across the room. The multi-speed fan features three different fan speeds for more cooling flexibility and 4-way air direction control allows you to direct the air where you want it. The antimicrobial mesh filter cleans the air, removing harmful bacteria. Plus, quiet operation keeps you cool without keeping you awake.
