Your Homes Ductwork and Insulation play a very important role in your home comfort. Leaking Ductwork can waste more than a third of the conditioned air that your system generates.
When your ductwork leaks, it lets pressurized air escape from your home. This in itself is wasting the conditioned air you are paying for but, it also places your home in a negative pressure letting dust infiltrate through all the small leaks in your homes construction. Properly sealed / installed Ductwork will keep your home at a slight positive pressure thus not letting dust, allergens and pollutants into your home. Also, most homes have inadequate insulation in the attics / crawlspaces and that causes your system to work much harder. It may not even keep up to set temperature on very hot / cold days.
