Fairly easy to install. Directions were not super clear. The machine works quite well, though can be a bit noisy. Not inside-the-house noisy, but you can hear the low rumbling of the compressor while its running. The directions that came with the unit for connecting to the SmartHQ mobile app had not been updated with the newer technology in the unit, so I had to reach out to support for help, but nice now that it works. I really like the design that allows it so sit below the window sill so you can still see out the window and allow more natural light in the house. We just replaced our windows right before purchasing this unit, and this was a good option to not bust up the brand new window frame.
