mine will get cold in about 15 seconds, but the hotter the interior of the cabin is, the longer it will take for the AC to cool down the entire cabin, because as soon as the cool air reaches the cabin, its overpowered by the heat, and is why on a hot day with a super hot cabin it takes so long for you to feel it.
now if your AC doesnt blow cold within a minute or so after startup, you have problems. Maybe needs recharge?
My vert is fast to cool as well.
They replaced a little valve @ the front of the engine a year ago and since then it will freeze you even in 94 degree's.
Sure it takes a few seconds to get cold but no longer than any other car really.
100 degree's might make even mine work hard
