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. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. 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 City, PA helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Spring City, PA, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

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. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in PA.

What Is A Passing Blower Door Test Score?

In Spring City, PA, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions.

Preparing for a Blower Door Test in Spring City, PA

We start the process of blower door test in Spring City, PA by ensuring all heating, air conditioning, and exhaust systems are turned off. 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. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. 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 Spring City, PA.
