[DML] Re: Air conditioning from R12 to R13

["doctor who" <ohwrd@xxxx>]

it is my understanding that changing the type of refrigerant grades requires 
a different set of nozzles to be installed in the compressor for max. 
refrigertion effect.

I also thought that federal law required a cfc permit pump the old coolant 
out of the system and to certify that there are no leaks before replacing 
the coolant.

i'm not a ase or hvac mechanic, but this is the info I got when I asked a 
friend about it.

my .05,
dr c.?
