How do you guys keep up with the Freon both R134 and R1234yf?
We know how to inventory them but how can you watch when the techs don't know how much they take out (and put back in)
They supposed to print out all the job but of course most of the time they forget about it.
These guys (techs) sometimes don't care about how much they use and sometimes just guessing. So we have no idea, why the freon we have are getting low, especially the pricey R1234yf.
