  1. If you attempt to recharge on the high side when the compressor is running it can blow up our can of r-134a. A normal can is somewhere around 100 psi or so (it depends on the ambient temp). The high side of an ac system can be around 250 psi. The refrigerant will NEVER tranfer from the can to the system. It’s pretty dangerous and not correct to charge on the high side. If you have a recovery/recycle machine like the dealer is using the charging is done with the engine and compressor turned off. With the compressor off it could be charged through the high side, but i don;t know many people with an ac recovery/recycle machine sitting around their houses nor do i know anyone who would modify their machine to reverse charge.
