The Importance of Sealing Air Ducts

An enormous waste of energy and increased operating expense 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 may be difficult to find without proper experience and equipment.
