air conditioner

I am thinking about rechargeing my rv air conditioner myself.I am not sure which side is the low or high side.Will the can connect to both sides or will it only connect to the low side.

  • If you don't know the high side from the low side, you should get a professional to do it.

    It has been converted from r12 to 134a.It is a 92 p30 chassis with a 454 big block tbi
    If you are going to attempt this, buy a refill kit that contains a shut off valve and a pressure gauge and follow the instructions.
    Shooting in the dark is not a good idea when you are messing with a 300psi system.
    That or have it done by a professional.

    If you do manage to hook up the high side to the can, you could end up with a blown up can......and a mangled hand.

    AC work is not just "stuff a can in it". You need to have gauges and know what you are doing.

  • R134 adaptors are sized differently between high and low sides. The standard refill can will only connect to a low side sized adaptor.
