Always on a Friday of course. this is an R22 low temp rack. Oil issue upon oil issue upon oil issue, after we fixed the last oil issue. Clogged TEV screens every 6 months. Stuck oil floats and so on and so on. I guess it generates a lot of business for the company...but what does one do to fix this on a long term scale? Convert the whole system to something else, right? Is there something we can convert it to relatively easy or no? New compressors, new TEV's in everything? What else?
