    Great window ac unit. This unit replaced another unit that I had but the only issue I had was that the specs were a little off. It’s slightly wider than it states. Still was able to use it but just keep that in mind if your limited with space.

    This thing heats and cools better than our central unit in the house! We use it in our detached game room. Installation was fairly easy but really took 2-3 strong people to get it in the window correctly.
