What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. 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. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Ardmore, PA makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Ardmore, PA, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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 pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

In Ardmore, PA, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. 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 Ardmore, PA helps improve energy efficiency and meet all local code mandates.

Preparing for a Blower Door Test in Ardmore, PA

We start the process of blower door test in Ardmore, PA by ensuring all heating, air conditioning, and exhaust systems are turned off. 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. 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. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Ardmore, PA efficiency standards.
