After the leak check is confirmed tight, then the vacuum is pulled, 10 oz isnt enough refrigerant to really break vacuum... and how are you vacuuming the system, then attaching a can? Vacuum needs to be treated with respect... itll pull in moisture if you swap cans, and hoses from the vacuum...

Itll pull in air and moisture if you disconnect hoses from vacuum...

A hard vacuum, then dumping in an entire can into the liquid side WITH THE COMPRESSOR OFF... would get oil into the condenser... then after pressures equalized, you could start the compressor and slowly flow the oil and refrigerant into the low side...

Agreed. You are better off having it done by someone with a recovery/recharge
machine, and it will be done correctly. There is too much guess work involved by using cans. If you want to use up the cans you have, your local A/C shop should have a way to recover the refrigerant from your cans, and credit you that amount when your car is charged by their machine.

Rich, where would I get the funds to pay for $90 an hour of labor? Last time had A/C work done at a D.Y.I., that is what they charged and messed up the system; rip off in many ways. I love to find that and get the guide rod mounts done. I seriously make $60 to $90 a week and don't have any credit options. And no, bills don't get paid. I have lived without water and electricity; they give a few months grace before shut off. Amazing how little we need in life.

My friend will charge me nothing and has done cans before, more than a couple, just don't want to lie about the amount.

But, if find a resource, change mind.
