What Our Clients Say
How Is A Blower Door Test Conducted?
For accurate blower door test in Pike Creek Valley, DE, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.
As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the DE climate.
What Is A Passing Blower Door Test Score?
In Pike Creek Valley, DE, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties.
