I took my Avaitor to dealship have AC blew out freon for second time in a few weeks. They stated The system was building pressure and blowing the freon out. They also stated that for $2600.00 They could fix the problem. $2600 is a fifth the cost I paid for the car 2 years ago. Its outrageous. Anyway, They said it was so costly because the entire system had to be replaced. Its a dual system so two of everything except compressor. They diagonosed this by from my understanding using some kinda pressure gauge. They didn't use any dye etc. Can it be fixed without replacing the entire system? Can they dye it, find leak and just fix that part? Someone told me the entire system must be replaced cause air gets in system and then I don't know. Must be a better/cheaper way to get it fixed or do I just need to "bite the bullet" on this one. Thank you so much in advanced. The advice herin on the website is priceless. Thanks
They can try soapy water, dye test or use a electronic leak detector to find the leak-Most leak repairs involve replacing O-rings, seals or hoses. But if the evaporator or condenser are leaking, repairs can be expensive.
Also have the system evacuated if it has air in it-
