The Energy Conservatory developed the Blower Door in the 1990’s to depressurize the home and calculate the amount of air leakage into the home from outside the “Building Envelope”. With this test running we can run further test to pin point leakage
The Minneapolis Duct Blaster is the master at identifying duct leakage. This test along with duct sealing can save you hundreds of dollars a year on Heating and Cooling costs.
This test can be used in combination with a blower door and/or duct blaster to determine pressure differences in wall cavities or other unconditioned parts of the home where we don’t want air being drawn from. Sealing a home based on the findings of a pressure pan test can improve indoor air quality greatly in addition to more Energy Efficient.
