Yes, it can be used while the A/C is running. It has a black fabric liner that holds the acoustic fibers tight. Choose the correct thickness! If the liner is too thick, acoustics material will impede airflow. Small ducts (less than 10") should use the 1/2" thick liner. Larger ducts (12" x 12" or more) should use the 1" thick version. Commercial ducts (18" x 18" or more) use the 2" thickness. For additional sound absorption, oversize your ducts (no more than 30%) to allow space for a thicker liner. Install the EcoVerb Roll acoustic liner with the cotton side facing the inside wall of the duct. The black liner faces out towards where air is flowing. The facing protects the absorptive cotton fibers from airflow. Recommended Adhesive: 3M Super 77 or equivalent
