What does duct leakage refer to in HVAC systems?

Duct leakage specifically refers to the unintentional release of air from within the ductwork of an HVAC system. This leakage can occur through gaps, cracks, or holes in the ducts, compromising the efficiency of the air distribution system. When air escapes from the ducts, it can lead to increased energy costs, diminished heating or cooling effectiveness, and an overall reduction in indoor air quality.

Addressing duct leakage is critical for ensuring that the HVAC system operates as intended, delivering conditioned air to the intended spaces while minimizing energy waste. By improving duct sealing and insulation, homeowners and HVAC professionals can enhance system performance, leading to more comfortable living environments and lower utility bills.
