DELLA 18000 BTU 20.5 SEER2 Floor Mounted Mini Split AC - Up to 1000 Sq. Ft.

We loved this mini split! It took a few days as we decided to take it through the attic to an inner wall, and our sons were only available on weekends. It is so nice and quiet, so many choices for options, and when I notice it is on, I find myself thinking, you are saving 30% or more. I also love that it works with Alexa, and on my phone to make it even more versatile. It was a great purchase. We love it!
