AC freezing up and compressor not cycling

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Your 2007 Chevy Silverado 2500 HD’s AC sounds like it’s trying to perform some sort of magic trick—freezing up and then poof! No airflow. This could be a sign of low refrigerant levels or an issue with the expansion valve. When the system gets too cold, it can freeze the evaporator coil, restricting airflow like a traffic jam on a Monday morning. Manually cycling the compressor helps temporarily, but it’s a band-aid, not a fix. Getting a pro to check the refrigerant levels and system components would be a smart move to keep your cool without the drama!
