What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Limekiln, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the PA climate.

Preparing for a Blower Door Test in Limekiln, PA

We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Limekiln, PA energy efficiency codes.
