Why is proper duct sealing important in HVAC systems?

Proper duct sealing is crucial in HVAC systems primarily to prevent air leaks, which can significantly impact the system's efficiency and indoor air quality. When ducts have leaks, conditioned air can escape before it reaches the intended spaces. This not only results in a loss of energy efficiency, leading to higher energy bills, but also causes the HVAC system to work harder to maintain desired temperature levels.

Additionally, well-sealed ducts can enhance indoor air quality by reducing the infiltration of unwanted air, which can carry dust, allergens, or pollutants from unconditioned spaces. This ensures that the air circulated within the premises is cleaner and more comfortable for occupants.

While making installation easier or reducing material costs might seem advantageous, they are not the primary reasons duct sealing is emphasized in HVAC practice. The impact on performance, efficiency, and the overall health of the indoor environment remains the most significant rationale behind ensuring that ducts are properly sealed.
