What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Perkiomenville, PA assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Perkiomenville, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in PA weather.

What Is A Passing Blower Door Test Score?

Construction in Perkiomenville, PA must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Passing this threshold during your blower door test in Perkiomenville, PA ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Perkiomenville, PA

We start the process of blower door test in Perkiomenville, PA by ensuring all heating, air conditioning, and exhaust systems are turned off. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve 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. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Perkiomenville, PA efficiency codes.
