Welcome! Here are the website rules, as well as some tips for using this forum.
I recently acquired a new (used) AC system for my house. Mitsubishi mini-split system with 2 zones.
It has been stored in a storage unit for about the last year, unfortunately the ends were NOT sealed off when removed.
How can I test it to make sure it works before installation? I have heard these systems are very sensitive to water even in the air....
I would like to make sure it works before installation as it will be quite a process....
What are my options?
Thanks in advance!!
