The answer to 'difference between air duct sealing and' is that air duct sealing and air duct cleaning are two separate HVAC maintenance tasks with different goals and benefits. Air duct sealing is the process of identifying and repairing leaks in the ductwork to improve the efficiency of the HVAC system. This helps reduce energy costs and improve indoor air quality. Air duct cleaning, on the other hand, involves removing built-up dust, debris, and contaminants from the inside of the ductwork to improve air flow and indoor air quality.
The key difference is that air duct sealing focuses on the physical condition of the ductwork, while air duct cleaning addresses the cleanliness of the ductwork. Both are important for maintaining a healthy, efficient HVAC system, but they serve different purposes. Air duct sealing is generally recommended every 5-10 years, while air duct cleaning may be needed more frequently depending on factors like home size, number of occupants, and presence of pets or other indoor air quality concerns.
