What Our Clients Say
How Is A Blower Door Test Conducted?
When performing blower door test in Felton, DE, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.
As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in DE.

In Felton, DE, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities.
