We originally had one air conditioner in our tiny home (and no central air), so some rooms were still pretty toasty in the summer, especially the ones with windows facing the sun. So, I took a chance and went with this air conditioner, and I haven't looked back since. There are lots of settings on this thing. Even when I don't use it as an AC, I'll often leave its fan on for noise cancellation and air circulation. However, in the summer, I love this thing. Put the blinds down, this thing on high, and kick back and enjoy a nice movie in the summer. After a while, you will need to clean the filter. This process is easy; just remove it and then wash it with soap/water and reinstall. Simple as that. Other than that, you don't have to worry about a thing. I highly recommend this air conditioner.
