Over the counter Freon recharge kits should be banned ; ill bet theres
been some lawsuits, but, evidentally, not enough. Us guys in the HVAC
trade have to be certified to handle refrigerants and most have us have
graduated from a 2-4 year Trade School. Yet consumers can buy and
dispense it into their cars a/c system without knowing anything about
the danger, how to determine correct charge, how to purge air from the
hoses, et al ??? Something is very very wrong here.
