What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Penns Park, 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?

While performing blower door test in Penns Park, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. 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. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

What Is A Passing Blower Door Test Score?

Homes built in Penns Park, 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 goal during your blower door test in Penns Park, PA promotes energy savings and demonstrates adherence to local building rules.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Install an effective air barrier, for example Tyvek or Zip Sheathing, and make certain all seams are sealed with durable tape.
Apply the correct R-value insulation and verify that it’s properly fitted to seal the whole building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Ensure all penetrations between conditioned and unconditioned areas—like attics, basements, and crawl spaces—are tightly sealed.
Local code departments usually provide a checklist to assist with compliance — see the Philadelphia example here.
At Local Energy Audits, we utilize thermal imaging equipment, caulk, and spray foam to identify and fix air leaks during testing./li>

Preparing for a Blower Door Test in Penns Park, PA

To ensure accuracy during blower door test in Penns Park, PA, we begin by switching off the HVAC system and all exhaust fans in the home. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Penns Park, PA.

Blower Door Test for Contractors in Penns Park, PA

For contractors arranging blower door test in Penns Park, PA, most homes with professional insulation can handle small air leakage issues during the test itself.
