    Fans on? Plastic bag wrapped around cond? Split coils? If fans on and coils clean start pulling charge. Agree with push it on the restriction thing

    There must be 50lbs in that thing maybe more. Way overcharged. Once removed she should run longer so you can begin to diagnose it.

    Reciprocating compressor, the compressor is about 3 months old, the air h is about 3 years old, there's a pic, hope it uploads.. The system may have been overcharged from what i understand about 2 weeks ago..
    Standing high side reads 200psi.
    Unless it is 100° where you are, that 200psi standing points to non-condensables......Just a thought.

    I vote for overcharged also but I bet there's another problem lying in wait also. Like maybe someone gassed it up more to keep the suction pressure up.

    Were you the one who changed the compressor?

    unhook compressor and let condenser fan run and watch the high side pressure. or verify that both sides are equal pressure. where is the filter drier? i had one restricted so bad not too long ago that the compressor hit 600 psi in 20 seconds

    It was actually way overcharged, so that solved high pressure 5 second run issue..

    Now it seems to be running right but can't lower low side line temp, its about 76degrees coming into the compressor.

    So right now my superheat is around 60, which is very high, I have reached 250psi on the high side while unit is running but the suction does not seem to be affected, remains at around 40psig.

    I think this is what the previous person that worked on it had, so whoever this was just kept on adding freon.

    RIght now my big issue is calibrating it correctly but just don't want to end up overcharging it like the last person did..
