This AC is so good that when my last one went out and the extended warranty had been expired for a while, I knew this was the exact one I wanted. Love the App that enables you to adjust settings from your phone and check the filter and smart diagnose any issues that might arise. I really like that the AC comes out of it's case, so you can install just the case first and then the AC unit. It cools well in the southern heart and humidity. Well worth the purchase.
