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 can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Huntingdon Valley, PA allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Huntingdon Valley, 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 fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Homes throughout Huntingdon Valley, PA are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. By meeting this standard in your blower door test in Huntingdon Valley, PA, you can enjoy lower utility bills and peace of mind with code compliance.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Huntingdon Valley, PA

We begin blower door test in Huntingdon Valley, PA by switching off the HVAC system and shutting down all exhaust fans throughout the home. 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. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected 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. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Huntingdon Valley, PA.
