If the rooms of your home have uneven cooling or hot spots, it could be the result of: Clogged filters: if your AC unit's filters are clogged, it can restrict airflow. This will cause the cool air to be distributed unevenly.Closed vents: If a vent is closed, it will prevent cool air from circulating to that area.Air duct problems: If there are any leaks or holes in your AC unit's ductwork, it could also be the cause of uneven temperatures in your home.
