The design and implementation of any duct sealing program should consider program goals, contracting, marketing, training, and quality assurance. Program Goals Management must determine a program's primary goal as a first step. Programs can emphasize space heating and cooling savings for customers, or perhaps peak reduction for the utility. A main priority may be to discourage fuel switching or to deal with high bill complaints. Whatever the goals are, they can only be accomplished when the technicians delivering the service are given a comprehensive procedure, adequate training, and time to complete the work.
Quality control is essential.
Since sealing ducts can reduce the dilution of contaminants in the indoor air, strict compliance with safety criteria is absolutely essential to ensure combustion appliance safety problems and other indoor air quality issues are solved prior to duct sealing work. Safety problems with the furnace, water heater, gas range, and gas clothes dryer and any other combustion appliance must be checked. Tests should establish that appliances are operating safely before retrofits take place. Since the crew's duct sealing work may affect the combustion product content and venting, the same tests must also be performed after work is complete. Launching a Program Past experience dictates that projects be started slowly before establishing full-scale production.
