HVAC

The answer to 'when to replace air duct sealing' is that air duct sealing should be replaced every 5-10 years, or sooner if you notice any signs of deterioration. Proper air duct sealing is essential for maintaining the efficiency and performance of your HVAC system, as well as ensuring good indoor air quality.

Over time, the sealant used to connect and secure your air ducts can dry out, crack, or become damaged, allowing air leaks that reduce airflow and energy efficiency. Replacing the sealing helps prevent these issues and keeps your HVAC system running at its best.
