Why is air duct sealing important for my HVAC system?

Air duct sealing is crucial because leaks, gaps, or poor connections in your ductwork can cause your HVAC system to lose up to 30% of the air it produces. This not only increases your energy bills but also makes your system work harder, leading to uneven temperatures and reduced indoor comfort.
