Cool down with this 12,000 BTU (8,000 SACC) portable air conditioner by Danby, perfect for cooling spaces up to 250 square feet. To help maximize your comfort, the 3-in-1 design: air conditioner, fan, and dehumidifier helps ensure you feel comfortable no matter the weather out! 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. In addition, the 24-hour programmable timer allows for better control of when the unit operates, enabling you to save on your monthly utility bill. SACC is short for Seasonally Adjusted Cooling Capacity.
