What effect does sealing ductwork have on HVAC system efficiency?

Sealing ductwork has a significant positive effect on HVAC system efficiency. When ducts are properly sealed, it prevents air leaks that can result in the loss of conditioned air as it travels through the system. This means that more of the air produced by the HVAC unit reaches its intended destination, whether it’s heating or cooling a room. By minimizing the amount of air that escapes through gaps and cracks in the ductwork, the system doesn't have to work as hard to maintain the desired temperature. This results in reduced energy consumption and lower utility bills, ultimately increasing the overall efficiency of the HVAC system.

Furthermore, sealed ductwork contributes to improved indoor air quality, as it helps to minimize the introduction of outdoor pollutants and allergens that may enter through unsealed ducts. By ensuring that the HVAC system works more efficiently and effectively, sealing ductwork plays a crucial role in both energy savings and comfort within the living space.
