It was easy to install and comes with everything you need. The only think I didn’t pay attention to was the electrical outlet is different from the regular one so I had to change it but it wasn’t hard at all. The unit isn’t noisy at all and cools down very well. We’ll see how it performs in the summer time but I’m excited for the new AC!
