Mike,
One other question to ask here is why did it stop cooling in the first
place. Was there a leak in the system and was that fixed? One other
thing that I would add to Emery list is to change all the O-rings. I
would put the green o-rings back in.

The problem that you will have is finding a shop to work on it. No
licenced shops in Michigan will install Duracool or HC12. Your only
option is to have the system cleaned and flushed dryer replaced,
vacuum checked and recharge with 134.

Contact me offline.
