What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Cheltenham, 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?

For blower door test in Cheltenham, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

Preparing for a Blower Door Test in Cheltenham, PA

Preparation for blower door test in Cheltenham, PA includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside 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. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Cheltenham, PA energy code requirements.
