Unit has no charge.............Old R12 system.........A lot of work to convert to a newer refrigerant.........Plus with all of the grease , I probably burn the place down..........Do not know if Hot-Shot  is the way to go......I am leaning towards Choice  R420A, but my parts house has not heard of it....Suppose to have the same P/T relationship, plus use the same oil.............I already have the Hot-Shot on hand........Anyone else use R420A ????.

I have used 420a as a drop in for 12 for a few years...always worked great for me...approx. 10% less than rated charge, if memory serves...

HotShot is fine.

Since you have it on hand,use it.

409A is another drop in replacement

 

Hot shot will work

 

True stopped using R12 in 1993-4 , so this unit is at least 19 years old

don't get married to it

I use hot shot for Old & new  R12 Or R134  also hot shot seems to clean small restrictions,  after charging add a "Leak Sealer"

 

unless u have a GE with the rusted return line witch normally u must replace due to the size of the HOLE (LOL).  Have used them for the last 2 years with %100 success.

 There are 2 types 1 is delivered by the oil in the system the other witch I prefer is delivered by the freon.   Many brands most are the same.
