What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Chester Heights, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under PA conditions.

What Is A Passing Blower Door Test Score?

Homes in Chester Heights, PA are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Reaching this target in your blower door test in Chester Heights, PA helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Chester Heights, PA

To get ready for blower door test in Chester Heights, PA, our team turns off the HVAC system and shuts down kitchen and bathroom fans. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Chester Heights, PA.
