"AC Flush"

I'm not even sure if something like this exists, or what to call it. Well, Summers basically here. I want my air to work the best as possible, clear all the dust and shit out the vents, and have a nice, clean, crisp cold AC. How would I go about doing this, or where would I get it done? And how much $$$

Thanks in advance..

first place i'd check if equipped is the cabin air filter. only the first batch of 01's had the cabin filters. they were deleted midyear. so check behind the glovebox to see if you have one of those. if you do, i bet its probably dirty. that filter catches alot of the dirt and having it clean will help with airflow.
