 Hi. I'm not sure what a sweep charge is. Thats a  new one on me. I'm assuming(ahh-um) that your unit is a split system with the evap (fan section) in a closet and the condenser (compressor section) ouside next to the house. If it is you probably have 5-7 lb of now contaminated refrigerant(R-22 & R-12). If you'd like to check the refrigerant U need it should be stamped into the name plate of the outside section.

Going by EPA regs that mixed refrig must now be reclaimed and disposed of(destroyed). It can't be seperated by U. Your system must then be evacuated well because the oil has probably absorbed some of the 12 into itself and has to pulled out. The the system will be re-charge with fresh R-22.

I think ur gonna have to bite the bullet and call someone. You might try posting a note at a local refrig supply house. Alot of guys do side work.
