This quiet and efficient 12,000 BTU portable air conditioner by Danby is perfect for cooling rooms up to 350 square feet. With its patented Silencer Technology, this model will operate at a quiet 45 decibels. Its four castors make this unit easy to move from room-to-room, and the single-hose design efficiently exhausts warm and humid air outside. The 24-hour programmable timer allows for better control of when the unit operates, which helps you save on your monthly hydro bill. To maximize your comfort at home, this unit is also equipped with a 3-in-1 design: air conditioner, fan, and dehumidifier, to ensure you and your guests feel comfortable no matter the weather outside! Also included with this model is a 24 month in-home parts and labor warranty. SACC is short for Seasonally Adjusted Cooling Capacity.
