This 10,000 BTU portable air conditioner by Danby is perfect for cooling spaces up to 250 square feet. 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 help 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! SACC is short for Seasonally Adjusted Cooling Capacity.
