I went to work on a rooftop AC on a moter home today.
It lost its charge,found the leak fixed it.Vacumed it out and was ready to charge it.I thought it was a R12 system I looked at the plate it said it was R22.
It is a very simple setup Its a hemetic sealed compresser the kind you would see in a refrigerator runs on 120 volts ac.Its a capillary tube setup.
My problem is I dont have any R22 and dont want to go to the big exspence of buying a 30lb jug of it.
Just wondering what would happen if i charged it with R12 which i do have plenty of that.
Or mabey one of you guys know of something else I can use?
It holds 20 OZ of R22
What can I do If I have to I guess I will get some R22
What would do?
