8 3/4 years. Still have 2 one tons in each of 2 bed rooms. Could not just order the inside mit unit; hvac guy told me had to upgrade the whole system to the current Mitsubishi system. Glad I found this solution.
thanks. I was hoping that was the case. This unit replaced and 1 ton Mitsubishi mr slim that was leaking freon. Because of the replacement, the holes were already made in the wall.
I just installed a costco 1.5 ton, 18000 Mr. Cool. Then I saw that I was to plug the unused drain hole. My unit is on the wall. Where is drain hole; googling it does not come up with it. I emailed Mr Cool, but this is Sunday and I would like to know today. Appreciate any help. Thanks
