    My AC condenser is leaking, so I am going to replace it. Does anyone have any advice or information on steps to replace? I have not been able to find any info on it. My AC shop said its pretty easy to do and he would handle recharging after I put the compressor in. Any info would be appreciated.

    Thank you!

    Swap it, add two ounces of PAG oil either through a can or manually pouring it in, install new o rings on the lines going to it, recharge the system. Simple as pie.

    Part of the recharging involves another step -- hook up a vacuum pump to evacuate air and moisture (also lets you know if there is a leak) before recharging. It would also be wise to replace the receiver/dryer.

    Yeah you should pull the vacuum but during a quick swap its been fine in my experience. If you can get the pump and have access to an air compressor then insert that step.

    Ok thanks guys. I am gonna swap the accumulator, orfice tube, and condenser. PAG oil in the condenser and accumulator before install? My AC guy said he would vacuum and recharge once I swapped everything. I figured he would put PAG oil in as well, but if thats a step I need to do before I put them in then I want to make sure and get that right.

    I would add it first, his may be straight freon with no oil in it (likely).

    In professional systems, the refrigerant and oil are kept separate. Any evacuations done in the machine separate out the oil.

    It wouldn't make sense to mix them as there wouldn't be any control over the individual quantities. Whether you add the oil or not is up to you, just let whoever is evac/recharging your system know so they can take the appropriate steps

    I would never charge any a/c system without first bring it to vacuum and make sure it holds for atleast 30 mins. Whats the point of charging a system that may or may not have a leak and has moisture inside it? Once a system is opened up it will suck in outside air that has HUMIDITY which is evil to your A/C System.

    These a/c systems use an accumulator not receiver/dryer but yes it also needs to be replaced.

    Thanks everyone for your help! I replaced condenser, orifice tube, and accumulator and replaced the o-rings. Took it to the shop and they vacuumed and recharged, everything blows cold now. He said there were no leaks so hopefully I should be good to go. The AC Delco condenser I ordered seemed kinda poor quality compared to the original one, but other than that it was all easy.
