A/C test and recharge estimate? on 2005 Ford Five Hundred

My car has auto temperature control. Worked fine in the winter. Now, the A/C does not seem to cool. I don't even feel an extra surge of power when i set the temperature low, like you do in cars without auto temp control. I want to start simple and have it checked and or recharged. How much will that cost?
