    We have no A/C!

    A little background on this call... Went here for a PM/startups. This unit had a bad LPCO. The way the contract was set up, NO repairs can be made on a PM without authorization. So, I noted it and left it (it wasn't warm enough to need it yet, anyway). Apparently, the tenant (a weight loss center) needed the cooling anyway (understandably). Since we are hired by the bldg. owner and not the tenants, they didn't know we were their service company, and called someone else. The landlord showed up while they were there, and kicked them out not thinking anything of it. Then we get an emergency call for A/C. This is what I found, only expecting to be replacing a LPCO, and having no idea another Co. had been out here. The funny part is, they had the transformer ripped out, and all the other wiring disconnected. What a mess. Got some nice overtime, though since I was sent at the end of the day, and it was supposed to be a quick fix. Had to rewire most of it, using a washed out, illegible wiring diagram.

    How many times must one fix something before it is fixed?

    Did the landlord catch them trying to fix it.
    Or trying to strip it.

    Trying to fix it, I guess.... but I don't understand why they had the transformer and half of the wiring out when all it needed was a LPCO. Apparently they had no clue where to start troubleshooting it, and just started replacing stuff randomly.

    looks like they bad the blower motor off as well. Seen it in the lower right hand corner.

    I didn't realize that was in the pic... we actually had that off because we had to replace the mount while we were there, too. My helper was working on that (his knee is in the pic, too) while I was working on the other mess.

    For some reason. Lots of guys don't think to check for safeties being open. They just start replacing any thing electrical that is in sight.

    That transformer hanging there looks like the transformer bandit struck that unit. You'd be surprised how many of those I see hanging by their wires when I open up an air handler or some other...
    Not as lean, not as mean, but I'm still a hardcore, ass-kicking, hard charging Marine! Oohrah!
