Most homeowners don't consider sealing the air ducts of their home-- but the process is crucial to keeping your house energy efficient. Ducts are what distribute heat and central air conditioning to the various rooms of your house, and often these passages have gaps in their connections, allowing the conditioned air to leak out before it reaches the intended room.

A significant amount of energy may be wasted this way. What's more, if leaky ducts are situated in spaces that get dusty or dirty, those pollutants can get sucked into the system and distributed throughout your home.

To reduce these scenarios from happening, make sure your ducts are sealed, either the old-fashioned way (by applying some tape, mastic, and insulation) or by hiring a professional to blow liquid rubber sealant through the system. In any case, having properly sealed ducts will help you balance the air temperature of your home and improve the air quality.
