How Can I Seal a Leaking Air Duct to Improve HVAC Efficiency?
You can seal small, visible duct leaks yourself, but professional duct sealing typically delivers better, longer‑lasting efficiency. Turn the HVAC off, inspect exposed joints and seams, clean the surfaces, apply a duct‑rated sealant, and replace the air filter. For hidden or extensive leaks, schedule our “Duct Sealing” service. Pairing this with “Ventilation Cleaning” can improve airflow. During new installs, we design and seal ductwork for quiet, efficient operation. Protection Plan members get annual IAQ inspections and 10% off HVAC service and repair.
