Recommend shop for a/c work in Chandler, AZ?

Howdy folks.

The 2006 that my wife mostly drives doesn't seem to have very cold air any more. I am going to swap out the cabin air filter, which has been neglected, today but I don't expect it to make (much of) a difference. I gather that Prius a/c systems cannot be treated the same as conventional ones and am thinking that a stealership might be the best choice, but there are a lot of Prii on the road so maybe there are good independent shops? Anybody know of one in the Chandler/Tempe area?

Thanks, Doug
