What must be done to existing ductwork when insulation is specified for installation of new cooling equipment?

When new cooling equipment is installed and insulation is specified, existing ductwork must also be insulated to ensure energy efficiency and optimal performance of the system. Insulating the ductwork helps to minimize heat gain or loss that can occur as air travels through the ducts, especially if they are located in unconditioned spaces. Proper insulation of the ducts contributes to maintaining the desired temperature of the air being delivered to different areas of the building.

This step is essential not only for improving system efficiency but also for compliance with various building codes and standards aimed at promoting energy conservation. In many instances, failure to insulate existing ductwork can lead to increased energy costs and may undermine the effectiveness of the new cooling installation. Thus, the requirement to insulate existing ductwork ensures a cohesive and efficient heating, ventilation, and air conditioning (HVAC) system.
