Evaluate your home’s air leakage and achieve energy compliance with precise blower door test in Jamison, PA. Our skilled technicians help homeowners, builders, and contractors find air leaks, increase comfort, and comply with PA energy standards.

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 many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Jamison, 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 carry out blower door test in Jamison, PA, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

In Jamison, PA, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Passing this threshold during your blower door test in Jamison, PA ensures both energy savings and full compliance with local regulations.

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.

Through blower door test in Jamison, PA, homeowners can easily find leaks. When the fan reduces internal pressure, air movement through problem areas becomes noticeable, offering chances to save energy.

Preparing for a Blower Door Test in Jamison, PA

For blower door test in Jamison, PA, preparation includes turning off all heating and air conditioning units, plus 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. 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 pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to 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. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Jamison, PA building codes.
