    Worst/ most costly mistake you've made on the job?

    Ever fall through a cieling? Cut the wrong hole? Broke a unit? I wanna hear your stories of major mess ups in the field!

    Thankfully I haven't done anything costly yet...

    One time I married a Sicilian woman. That cost me almost half a million - and that was back when a half million was Serious Money. That's about my most expensive field error.

    I never married a Sicilian woman.

    I was working with a former employee years ago, and we were splitting a coil on a Lennox GCS unit, and we hadn't opened the coil very much when it started to hiss....

    A few months ago, I was on a roof with a guy where we successfully cleaned a Carrier, also splitting the coil.

    I turned my back to talk to a guy from another company, leaving the helper to put it back together after removing the prop for the top. I said, make sure you put the screws back in the same places....

    Once again, hissing.....

    Hmmmmm. Remember when carrier first came out with the two stage Bristol compressors? I figured one contactor for comp. One for cond. Fan. Press them both in and make sure it works. Nope. Not anymore​.

    I rolled a WSHP through someone condo over their hardwood floor on a brand new dolly that had something stuck in the wheel. I left a trail of dimples across the whole floor.

    Let's see, after pumping 5 ton unit down for some reason, I was putting a new drier in and melted the LL service port and was not smart enough to figure out how to reclaim the 22 at the time.... put a new compressor in cause it was showing open, it was open limit cause the cond fan motor was bad. Reclaimed what I thought was the correct unit and then when I went inside and started cutting the txv out realized I did the wrong unit.

    I can go on lol

    Just pick one?
    Working at a church, 2 oil furnaces, 2 pipe setup, doing PM's. I opened the valve on the supply line but forgot to open the valve on the return line. I flicked both units on to do combustion testing. 3 seconds cost me 2 new fuel units and about 3 hours time. Grrrr.
    If I do a job in 30 minutes it's because I spent 30 years learning how to do that in 30 minutes. You owe me for the years, not the minutes.

    Was sent to a large hotel to try to fix one of their room a/c units. I pulled the thing out of it's sleeve and set it down on the carpet and started troubleshooting. I found that the t-stat was stuck open, so I jumpered the thing out and plugged it back in.

    As soon as i did there was a big POW, the lights went out, and a big sooty mixture of oil and refrigerant started to spray all over the place.

    I think what happened was the compressor was shorted out and the t-stat was the weakest link so it burned open. When I jumpered it out it caused the terminals to blow out of the compressor.

    To make matters worse, this was a new customer that my boss had been trying to get his foot in the door at for a while.

    He ended up buying them a new air conditioner and paying them extra to replace their carpet. Needless to say we didn't ever end up getting any extra work out of them like he was hoping.

    Was working at a Marriott, and was replacing a compressor in a Dessert Aire A/C / Humidifier. I recovered about 50 lbs of R22 and took out compressor and put new one in. Went to go un-braze filter drier to replace and suddenly refrigerant and oil erupted and clouded out mechanical room and hallway. Probably about 30lbs r22. I had never come in contact with a three way valve as I was
    still a bit green and boy did it take me by surprise.
