I like the AC's and dehumidifiers at work. Doing the breakdown keeps my hands busy on the slow days. It took a little bit of practice but i figured out how to separate the sealed unit and al/cu radiators from all the other stuff without breaking any lines. It makes it easy for the Freon removal technician to pump out the Freon and the oil in the sealed unit. It's all good scrap metal for the recycling yard after he has done his part.
