When I turn on my air conditioner there is a banging sound in my dash board. Sounds like something is hitting the dash underneath. It stops after about 30 seconds

Does It sounds like water hammer in your house pipes?that's what it is only with freon, you should get a can or two of freon, with the Gage and filler hose with it, and check your freon level, it's probably low on freon.. It would sound like a hiss, if the freon was leaking from under the dash. mine use to leak right behind the radio, at one of the connections, and hissed after i would turn the van off for a few mins....hope this helps
