I was a highly skilled and experienced home service professional who was called to a job to balance the dampers and measure the CFM from each vent in the home. I started by climbing into the attic to balance the dampers, ensuring that the air flow was evenly distributed throughout the house. Once the dampers were balanced, I moved inside the home to measure the CFM from each vent. I used a specialized tool to measure the airflow and ensure that it was within the recommended range for proper ventilation. I also checked for any leaks or obstructions in the ductwork to ensure that the system was operating efficiently.
