Yeah, he is. Think it'll be a while before he's in his own truck though.

You will find out what breaker that's on in a hurry!

I can't even see any dumb logic here, that's completely willy nilly

Schools these days just tell the students they are there so they can prepare to learn....they hit the job site not knowing a thing. the trade schools in my neck of the words are a scam.

Pretty sure most guys fresh out of school would do bad at that test. They do not teach like they use to. Tech schools have become little more than money making scams that have kids thinking they will be able to start running service when they graduate, and believe me they all graduate.

Even the test in post 10 favors theory. Apprentices used to hook up with a journeyman during the day and get schooled at night. This was supposed to balance theory and practice. The handful of good techs I've known didn't wait for knowledge to be handed to them. They took it on themselves. School is never enough.
Many journeymen of the past didn't have a lot going for them either. There was a bunch of bad information out there. Beer can theory in many ways.
We all have heard comments about a young couple going into the world and people saying "They will never make it" Most do somehow.

Being an electronic engineer in my previous life, the teachers in my local tech school are pathetically lacking in theories. One ridicules comment I remember goes like this " in a well designed circuit, a load will use up all the voltage between L1 and neutral..."

He needs to undergo all fundamentals of basic electricity, sad to say :-(

Got to love political correctness. Lord knows we can't let anyone know they aren't very good or are stupid.

#12 charge it with frezone until its "beer can cold"

One word... pathetic.

#12, the evaporator is below freezing and making frost/ice, high side is a little too high, get the tequila and margarita mix ready, it's going to be a good day for someone. (I don't drink)

thats right folks...2sac will be here all weekend, happy hour starts at six, two for one specials, and dont forget to tip your waitress

11. The house isn’t cooling, inside and outside unit is running, what is the first thing you do? Why are there so many questions about tequila and margarita mix?
12. I have an 80 deg day with an R-22 system, the pressures are reading 240 on the hi side and 50 on the low side-is there anything wrong and if there is, what is it? 80-22=58 low side is 50. I need to add 8lbs Freezone so low side will be 58

I agree. That’s how I got my start. Went to school at night and rode around as a helper during the day. Picked up the trade real quick plus I got to teach some techs some things they've forgotten or got lazy on through the years.

How about chasing them down and bring them back and tell them to get back to work.
