Duct pressure testing
Did you know that leaking supply ductwork causes expensive conditioned air to be wasted and dumped into your attic, crawlspace or garage instead of into your house?
Leaks ducts in forced air systems are now recognized as a major source of energy waste in both existing and new houses. Studies indicate that duct systems leakage can account for as much as 25% of total house energy loss, and in many cases has a greater impact on energy use than air infiltration through the building shell.
By now most counties and cities in our area have adopted the International Energy Conservation Code, IECC and the requirement to conduct Duct Pressure Test to new ductwork constructed outside the insulation envelope of your house.
