Should you shut the air conditioning ducts in basement since it is already cool down there?

The air conditioning system is designed to circulate air throughout the entire house, including the basement. Closing the ducts in the basement will prevent the cool air from reaching the basement, causing it to become even cooler and potentially damage the system.

Additionally, closing the ducts can lead to a build-up of moisture and humidity in the basement, creating a favorable environment for mold and mildew growth.

Therefore, it is recommended to keep the air conditioning ducts open in the basement to ensure proper airflow and prevent any potential issues.
