A duct leakage test is a test we perform on the HVAC duct lines to calculate how much they leak. We can perform this test for consulting, codes, and Energy Star. This test is mandatory in 2009 IECC, 2012 IECC, 2018 IECC, and Energy Star Homes. This test is very important, and we find all kinds of issues in homes that have leaky ducts, and it doesn't just consist of high energy bills or uncomfortable homes. Poorly installed duct systems cause pressures in the home which will cause a vast array of problems and some of them can be deadly. The HVAC system will not perform properly and duct leakage can be detrimental to the structure of the home. We see flooring systems rotting out from leaking ducts, roof decking rotting out, moisture issues inside the home, condensation and mold growth, back-drafting appliances, and many more issues created by this problem.
When should home owners have their system tested? There are tons of reasons but we will list a few that we believe are important points.
-Any time you believe your house could be more efficient.
-Building a new home.
-There is high humidity in the house
-You notice unusual amounts of dust.
-The color of your paint changes color around your supply ducts
-Hardwood floors buckle around supply ducts
-You notice condensation on your windows or other random places in the home.
-Having your duct work cleaned? Leaky ducts will only suck in dirt, insects, insulation, debris, pollen, ect.... Do not have your ducts cleaned before you have them tested and sealed! It will do you absolutely no good.
