Mr Cool 18000 BTU 5th generation mini split system

The Mr Cool 18,000 BTU mini split system 5th generation system is working great. I was able to install it myself with the included step by step instructions. I also went with the Mr Cool line cover plates to protect the lines but to also give it a clean finished look.

My Thoughts, that's all....

I have had a super good experience with Mr Cool, from before questions on 'chat' to ordering and after installation questions. No doubt I would do it again.
