What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Cedars, PA helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Cedars, PA, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the PA environment.

What Is A Passing Blower Door Test Score?

In Cedars, PA, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Achieving this standard in your blower door test in Cedars, PA lowers utility bills and guarantees adherence to local code requirements.

Why Do I Need A Blower Door Test?

Following the IECC guidelines, PA and many local jurisdictions require blower door test on newly built or renovated residential dwellings.

Place insulation with the accurate R-value and check for proper installation and full coverage in the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close and seal every opening between heated or cooled spaces and unconditioned areas such as basements, attics, and crawl spaces.
Most building departments provide detailed compliance resources — view the Philadelphia checklist example here.

Preparing for a Blower Door Test in Cedars, PA

Preparation for blower door test in Cedars, PA begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Cedars, PA.
