My 09 Camry hybrids air isn't blowing cold and I have kept all maintenance on it

Gradual or sudden change? My guess-gradual change=refrigerant leak over time. Have it charged with dye at a shop so they can find and repair the leak. --Sudden change-maybe electrical issue , again , more effective to have it tested at a shop , unless you have the equipment and skill/knowledge/info or whatever you'd call it. Good luck , yeah been to Arizona one time ...........it's a 'dry heat' , yeah , riiiiiight! HOT IS HOT ...
