As a home service technician, I recently completed a job that involved adding or cutting in a new supply duct to improve airflow and comfort in the customer's home. Upon arrival, I carefully inspected the existing ductwork to ensure it was in good condition and properly installed. I then proceeded to install the new supply duct, ensuring it was properly aligned and connected to the existing system. This not only helped improve the airflow but also boosted the system's efficiency, leading to lower energy bills and improved indoor air quality for the customer and their family.
