What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Spring House, 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?

When conducting blower door test in Spring House, PA, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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 expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. 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 built in Spring House, PA are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Achieving compliance in your blower door test in Spring House, PA helps improve energy efficiency and meet all local code mandates.

Preparing for a Blower Door Test in Spring House, PA

Getting ready for blower door test in Spring House, PA involves turning off all heating, cooling, and exhaust ventilation systems. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. 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 the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Spring House, PA.
