The Importance of Sealing Air Ducts

In many homes, duct leakage is the main cause of Indoor Air Quality problems, as leaks pull contaminants and irritants directly into your house from your attic, crawlspace or garage.

An enormous waste of energy occurs when cooled air escapes from supply ducts or when hot attic air leaks into return ducts. Recent studies indicate that 10% to 30% of the conditioned air in an average central air conditioning system escapes from the ducts.

For central air conditioning to be efficient, ducts must be airtight. Hiring a competent professional service technician to detect and correct duct leaks is an excellent investment, as leaky ducts are difficult to find without proper experience and test equipment.
