AC Re-Charge Does Not Hold

I went twice this summer to charge my AC paid almost $200, it holds for about 2 weeks and needs recharge again. Does anybody know where it leaks most often and can it be fixed without going to mechanich shop?

Also does those recharge kits that contain "sealer" help with this or its just marketing?

not necessarily in order, compressor hi press or o-ring, condenser, condenser line to receiver o-ring, condenser hi pressure input o-ring, the least likely but possible, the evaporator coil.

Put a charge with UV dye in and try again. Be sure to have a clean engine to start with. If your loosing your acís 134 that quick, there will be visible UV stains to see.
