At what point do you call out your coworkers and tell them to straighten up. I went to a call today for a keg cooler today. I arrive on site to find a blown breaker for condenser. While I'm looking around I find evaporator thermosat set to 10 degrees. Wires hanging loose with wire nuts all over the place. Solenoid coil overheating because screw is loose and wire connections look atrocious. I was embarased to say it was a coworker that did this. Then I find the wrong fan blade is installed and is going backwards. But i reset the breaker for condenser and it immediately trips. I go to roof to find compressor shorted to ground. So i qoutr the condenser pick it up and install. Clean up wiring inside the box while i evacuate and install proper fan blade and redo drainline that was taped to pan with electrical tape. I go back to roof charge system and find I now have a bad txv. Back downstairs and look at my danfoss valve and it is ziptied to suction line not insulated and at 12 oclock. So I move to approx 7 and insulate and open all the way up and can still only get 40 degrees superheat but much better than pumping into a vacumn as it had been. So i ordered the new valve.oem along with new evaporation motor because that wrong fan blade had worn out the bearings. I'm sorry for my terribly long run on sentence and if i was unclear let me know. But what a terrible day fixing somebody else's crap. Should I just stay quiet or should i tell the boss that one of his favorite super techs is a hack. The hack part is just my opinion.
