Subject:      Re: AC High Side - line leak - rubber hose

I made the mistake of telling the mechanic at Midas ...
"Just fix it "
I think he evacuated the system,
Put a vacuum on it
and topped off the R-12.
Charged me $90 bucks for a 12oz can. ( 3 cans = $270 )
I'm paying $20 - $25 on Ebay.
Total bill was over $600.00 Ouch !!!
Stayed "Real" cold for about two weeks, then just kinda cold :o(
Get an estimate. Still it will be pricey !
