Midea 12,000 BTU Smart Inverter U-Shaped Window Air Conditioner

I'm selling my gently used super Quiet U-shaped window air conditioner with energy-saving inverter technology, built-in air ionizer, and smart app control. Cools up to 550 sq. ft. with quick 3-step installation and the convenience of keeping your vertical sliding window functional. This AC was built for a vertical sliding window. I installed it on a horizontal sliding window, and it worked perfectly. You need to spend more time sealing all the holes, both inside and outside, when installing it on a horizontal sliding window. I bought it $650 two years ago.
