I have a friend in the auto repair business,he does everything from a tune up to engine swaps,etc.He used to do AC work,but gave it up after a few years,because most people dont want to spend the money to properly fix the system--most would say just re-charge the system,and not want to spring for a new evaporator core or valves and O-rings--then complain when it blows warm air two weeks later after spending 100 bucks or so--that and the fact that he machine they require you to have now to recycle the freon is about 5 grand,and the hazardous waste disposal fees discouraged him from wanting to keep doing it.Plus here in the northeast,you only really use the a/c about a month or two out of the whole year.I dont mean to discourage you from starting a business,but be aware there are lots of expense for equipment.My freind would have done better in a warmer climate probably,and it seems if you want to do AC work,its better to be a specialist and do only AC,not be a full service repair shop. I applaud you for having the ambition though--wish I had some!. /forums/images/graemlins/crazy.gif
