I needed a solution for keeping cool in my 220 sqft. office barn/shed (since working remotely) during the hot Texas months. Keep in mind that although this unit is portable, it still needs access to a window for the hose. That being said, it's working great and has no issues keeping my workspace at a comfortable 70-74 F (possibly lower, but was not necessary) with minimal noise. The remote allows me to change the settings from my desk without having to get up. Also great to have as a backup for the house if our A/C ever fails.
