I understand your concern, but this is a DIY forum. people come here to save money, or they simply don't have the money and hope they can do the repairs themself. In fact, there are a lot of repairs can be done easily by home owner. for example install t-stat, clean drain line, replace filter.., for more handy people, they can clean coil, replace contactor or capacitor, etc. it is all depends on how much they are capable and willing to do. To spend $79 to call a pro, then $240 to replace a contactor, another $200 to charge freon, $300 if it is R22... If they can afford all these expenses, they won't be here on this forum.
