Welcome to BlowerDoorTester.com My name is Eli and I am certified to conduct Blower Door Testing, Duct Leakage Testing and Air Barrier and Insulation Audits. As you may know the State of Delaware has adopted the 2015 IECC (International Energy Conservation Code) to require a Blower Door Testing for all new residential dwelling units in the state. If any part of the HVAC system such as the Air Handler or the Ductwork sit outside of the buildings’ thermal envelope a Duct Leakage Testing may be required as well.
As of 2018 Delaware has begun enforcement of the 2015 IECC, Internation Energy Conservation Codes requiring Blower Door Testing and Duct Leakage Testing and I am conducting these for contractors in Delaware. If you run into this and require my services don’t hesitate to give me a call. I price my services fairly and provide discounts for multi system and multi unit buildings. I carry practical tools on the truck like duct seal, tape, chalk, weatherstripping and spray foam. I always do what I can to achieve successful results.
Blower Door Testing is conducted by installing a frame onto a central door in the home and attaching a fan to the door. The fan depressurizes the home to a Pascal of 50. Once the home is depressurized we use an instrument called a nanometer to measure the difference in air pressure between the outside of the home and the inside of the home. We get results in ACH or air changes per hour. This is the amount of time air leaks a home and new air enters the home in an hour. All homes leak and thats normal but keeping air changes to an acceptable amount is important since each air change creates a need to reheat or cool the new air.
