Lol so one of the condo high-rises I service was replacing the unit number tags on the condensers. I've been complaining about it for 2ish years. Get a call from the management team saying one of their maintenance guys stepped on a big copper line (pic 2) and something started spraying out. Finished up the call I was on and headed out there. When I get there they take me to the unit and say it can be repaired right? I said well let me take a look and I'll come down and let you know what's going on. I noticed a ton of oil on the motor and fan blades so I pull the screws out to take the top off and it seems to be holding on still. Figured I missed a screw checked nope and then saw the number plate was screwed in. Unscrewed both and one self tapper was a half inch the other was 2" long bastard right into the coil. Unit being 12 years old and owned by the resident I got the manager and resident and explained what happened. And that what seems likely to have happened was the maintenance tech used a screw way to long and drove it into the coil scared him so bad he jumped over the unit and landed on the suction line. Or he just bent the suction line until it cracked and let a little oil out. The resident is now getting a brand new condenser and I showed the maintenance tech how to use a little brake clean so he could use the 3m tape that comes with those tags. Best job I ever had.
