Re: [DML] Loading R12 in A/C system

["Tom Niemczewski" <tomcio@xxxx>]

First a vacuum pump should be used to remove air and moisture from the
system. It takes about 20 to 30 minutes. Then he should charge the system
with 2.2 lbs of R-12. No A/C system will turn the compressor on without
proper pressure. May I suggest that you stay away from that mechanic? He has
no idea how the A/C system works.
Hope this helps.

So the mechanic refused to replenish the system!
