had a shop refill the freon about a year ago and now its not blowing cold. i doubt that i'm already out of freon because i got my honda AC refilled by the same shop 3 years ago and it's still blowing cold. do anyone have an idea what the problem might be?

 

you dont really lose that much freon unless theres a leak. have them check for leaks especially around the shrader valves. need a machine to put the system into a vacuum

 

Thanks. I'll look into that
