Central heating and cooling systems use an air distribution or duct system to circulate heated and/or cooled air to all the conditioned rooms in a house. Even when properly designed, duct systems must be installed correctly to be efficient, maintain uniform temperatures throughout the house, operate quietly, and not adversely impact comfort or indoor air quality. WHY DUCT INSTALLATIONAND SEALINGARE IMPORTANT – The efficiency of air distribution systems has been found to be 60-75% or less in many houses because of insufficient and/or poorly installed duct insulation and leaks in duct systems. Properly designed and installed duct systems can have efficiencies of 80% or more for little or no additional cost, potentially saving a homeowner $50-200 or more per year in heating and cooling costs. Moreover, efficient duct system installations can reduce equipment size, further saving money for new or replacement equipment.
