The Cool-o-matic tech came today and put 375psi of Nitrogen on the system. bubble tested the usual places, nothing.
the needle didn't move in the hour the gauge was on it. checked the schrader valves, all good. no sound of air leaking.
he suggested i look around, and he'll come back on friday morning and put the gauge on it. see if it leaked.
if not, he's going to put in dye, and r410b (which replaces r22 at 1/2 to 1/4 of the price) - and see what happens.
here for less than an hour - so $100 - fras-air charged $100 to tell me it didn't work, and that it needed replacement.
the guy had a solid road map to making decisions.
he said theft of r22 - especially since both systems were down - would not be unheard of. also, a kid playing with the
shrader valve isn't unreasonable. so is my kid snorting freon?
I thanked him for being a tech and not a sales guy. and he said here is how some of them work....
the aj perry people work on commission. the techs are not really techs, they are sales people.
