The 2012 IECC (International Energy Conservation Code0 403.2 regarding the installation of HVAC Air Ducts was a major leap for Maryland in Energy Efficiency. With the introduction of the Air Duct Testing, Maryland gave the responsibility to each County (Caroline, Dorchester, Kent, Queen Anne, Somerset, Talbot, Wicomico, Worcester) to ensure that all new duct systems installed are tested using the duct blaster. With this advancement in energy efficiency code, Delaware Residents are closer to achieving the Fifth Fuel "Energy Efficiency".
To meet the 2012 IECC Duct Code all duct work needs to be sealed and tested by a BPI Certified Contractor and be within the allowable leakage rate. Dave Lawson, owner of Dr. Energy Saver Delaware is a certified BPI Professional! The 2012 code requires all duct work located outside the thermal envelope (Attic, Vented Crawlspace) to be tested. The duct blaster testing can be done at one of the two stages (post-construction or rough-in) but most towns require the testing to be completed during rough-in to ensure that any leaks can be fixed before Insulation and Drywall are installed. The second method post-construction is generally used for retrofitting new duct work in older homes and also allows a blower door to be used to determine the leakage to outdoors.
