This will usually be in a basement or crawlspace depending on your ductwork. Make sure you open every vent in your home so you can check the airflow in each room.īefore you change your vents, you need to find the damper lever which will be attached directly to your duct. From these vents, you can adjust the amount of air flow to specific rooms that are connected to that vent. You can control your airflow anywhere that you have an air vent (the same place you go to change your filters).
