re using r22

if i was changing out a r22 condenser that has had no burn out would i be better off putting new freon back or is it ok to pump it down and hold it, then put it back in after installing unit. never did this, just a thought the new unit is a dry charge .this is not going to another property it is a swap out at same home.

    As a general rule

    I will always introduce new refrigerant that I KNOW is contaminant free,Especially when using new equipment.  Manufacturers will void warranty is they find out that new Virgin ref. was not used.  With new Ref. you know it is free of moisture, contaminants, etc...  You never know who worked on the system last.
