The answer to 'what does air duct sealing do' is that air duct sealing is the process of identifying and sealing leaks in your home's ductwork. Ductwork can develop cracks, holes, and gaps over time, allowing conditioned air to escape before reaching the intended rooms. Air duct sealing helps improve the efficiency of your HVAC system by reducing these air leaks and ensuring the heated or cooled air is properly delivered throughout your home.
Sealing the ductwork can provide several benefits, including lower energy bills, improved indoor air quality, and more consistent temperatures in each room. It helps your HVAC system work less hard to maintain the desired temperature, saving you money on your utility bills. Proper duct sealing also prevents dust, allergens, and other pollutants from being drawn into the ductwork and circulated throughout your home.
