No this is not normal.......it might take a minute or two to get cold.........but not ten minutes.
You should first inspect the freon charge.....as it might need some freon (gas).....
If the A/C system was not serviced for a few years, then i recommend that you withdraw the freon in it.....then vacuum the system, and then fill the correct quantity (weight)......this can be done on automated A/C machines, and should ensure that you get the optimal performance, regarding the freon charge.
Thank you for trusting JA and myself.......get back to me if further info is needed.....positive feedback and bonuses appreciated...http://www.justanswer.com/car/expert-billy/
