What Our Clients Say
How Is A Blower Door Test Conducted?
For blower door test in Bear, DE, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.
When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the DE environment.

Properties in Bear, DE must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally.
