My son in law is an electrical technician at a big network operations center. Because there are so many cooling units keeping the building at temp for all the servers there, months ago his work decided to send him to school to learn how to fix air conditioners. He now has a HVAC license. How nice we all thought. A skill to fall back on. The part we couldnt understand is that after he got that license, his work sent him to refrigeration classes. I spent months babysitting my grandsons while he learned how to fix refrigerators and freezers. Everyone thought that was strange, besides the break room fridge at work, we couldnt see why his bosses felt he needed this skill.
He has been finished with the refrigeration classes for about 3 weeks now. Yesterday I noticed that my fridge decided that it needed to hold a nice toasty temp of 62 degrees Instead of calling a repairman, we called the SIL. Yippee! The part the fridge needed only cost $30 and SIL refused to let us pay him for his time. Nice to have a refrigeration person as part of the family. I really like his bosses and their decision to send him to school
