    i don't care about a time limit,
    take your time and do it right or you'll be going back on it.
    chances are after you put the compressor in,what ever killed the first one will show it's ugly head,then you'll have to deal with that.

    It shouldn't take to long if you can lift it in and out with a crane (2 guys 4 hours?) But after it's in and running check operation press.,temps,etc. and be sure to clean the txv bulb if there is one and makesure it wasnt a burnout.

    Depends on how long it takes you to recover the charge, type of failure, repairing the reason it failed (not the compressor was old and worn story), leak testing, evacuation, etc. I think 16 to 24 man hours is reasonable depending on how things go. JMHO

    if you flip the old with the new right out of the unit and it wasn't a burn-out and you have service valves it should be running by noon the latest with a 8AM start.if it was burn out 2 days with many oil changes cycling the acid out with those oil changes...and installing a HH suction core filter set-up,and LL also.

    16 hours on a perfect day. 40 hours on a bad one.

    It will take 4 hours just to recover the juice, another 4-6 to replace contactors and wiring, 2 for the first drier change, 4 for the crane and tooling with a 2nd guy at lift time, 6 hrs to find that one fitting you didnt need anyways, 6 hrs to go back and forth to the truck half a dozen times and for lunch, 3 to run to the supply house again, 2 hours to chat with the gal in the lobby intermittently, 1 hour to chase away the maintenance guy and 2 hours to find him again. 4 hrs to install comp. 2 hours to recharge, and 3 minutes to watch it fry on startup because some external control was at fault, another 4 hours to get out of the building because someone forgot you were on the roof turned out the lights and locked the place up.

    12 hours for the new unit because you dont wanna go through that again.

    First question:
    Why did a 30 ton comp go bad?
    Second question:
    How long will it take to change out?
