Cooling load for residence in hot climate, system not showing energy output at night

I am working on a residence in Arizona, near Phoenix. Summer temperatures are hot even throughout the night. When setting up the model the cooling system never operates at night unless I start making the setpoint 65F or lower. Am I missing something? This doesn’t seem realistic. As an Arizona resident, the AC always kicks on throughout the night.
