how does air duct sealing work

HVAC

The answer to 'how does air duct sealing work' is that air duct sealing is the process of identifying and sealing any leaks or gaps in your home's ductwork system. Leaky air ducts can cause significant energy loss, leading to higher utility bills and uneven heating and cooling throughout your home. Air duct sealing involves using specialized sealants and materials to close these gaps and improve the efficiency of your HVAC system.

The process typically starts with a professional inspection to identify the areas in your ductwork that need to be sealed. They will then use a combination of mastic sealants, metallic tape, and other materials to create an airtight seal. This helps to prevent conditioned air from escaping and unconditioned air from entering the ducts, ensuring your HVAC system operates at its full potential.
