Danby 14500 btu officially cools spaces up to 700 square feet but worked great in my 1,200 foot top floor, model DAC145EB6WDB-6, in window air conditioner with remote and wifi. 2 years old, used maybe 20 days total so I’m happy to give a personal warranty on it. Like new in the original box as I got a heat pump shortly after purchase. Energy Star® compliant, Wireless Connect (using an app), Follow Me Function. Website: https://www.danby.com/products/window-air-conditioners/dac145eb6wdb-6/ Paid $706 after tax in the spring of 2022 so hoping it will be worth $300 for someone instead of sitting as a backup in my basement. Thanks for looking!
