Let RCA innovation and quality keep you cool and comfortable this summer. Our 3-in-1 portable air conditioner is designed for cooling rooms up to 300 square feet. The 3-in-1 operation includes cooling, dehumidification and a fan-only function. Key features include digital controls with LED display, 24-hour digital timer and a full-function remote control allowing you to control this unit from across the room. Caster wheels easily roll the unit from room to room and the included window venting kit makes setup quick and easy. In October 2017, the Department of Energy implemented a new test procedure to determine the BTU rating of portable air conditioners. The procedural change has adjusted the amount of BTUs allowed to be claimed downward by as much as 50%. There have been no internal changes to these units, and the functionality remains the same. Please refer to room size guidelines to find the portable air conditioner that best meets your needs.
