What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Avondale, PA, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in PA weather.

What Is A Passing Blower Door Test Score?

Homes built in Avondale, PA are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Achieving this standard in your blower door test in Avondale, PA lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Avondale, PA

To prepare for blower door test in Avondale, PA, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. 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 sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Avondale, PA.
