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. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Bechtelsville, PA locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Bechtelsville, PA, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the PA climate.

What Is A Passing Blower Door Test Score?

Houses in Bechtelsville, PA are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version.

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.

Preparing for a Blower Door Test in Bechtelsville, PA

For blower door test in Bechtelsville, PA, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Bechtelsville, PA.
