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.

GioP - Thank you for your five star review. We appreciate your feedback regarding our installation instructions and opted to cover the line sets with Line Guards for added protection from the elements. Thank you for taking the time to leave your comments.

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.

Great value for the price

I purchased this 2 zone 18000 btu mini split system from HD 6 months ago. It was easy to install. I had a local HVAC contractor do the final inspections. They pressurized and evacuated the system to verify no leaks. Once that was complete the added the refrigerant and tested the system. Up until now I have been using it primarily for heat. But summer is coming and it appears to work great on cool as well. My local contractor was impressed with the design of the unit and how easy it was to finish installation. So far the unit has worked great.
