Hello Jerry4kool. Thank you for reviewing the Toshiba 8,000 BTU Portable Air Conditioner RAC-PD0812CRRU. We are sorry that your new AC is not cooling your space as you would like, and we can help. Check that the exhaust hose is installed correctly through the window and that doors, vents, and windows are closed. If this is the first AC used in that space this year, give it a few more days to equalize as it decreases the Relative Humidity. During this time, increase the temperature to warmer than the coldest setting. A newly-installed unit first removes ambient moisture from walls, ceiling, and fabrics. Also be sure to set up the Continuous Drain. For additional troubleshooting, reach us at ToshibaCustomerCare@hartehanks.com and reference case number 111291326. Have a great day!
