What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Oaklyn borough, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Oaklyn borough, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

In Oaklyn borough, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Meeting this level during your blower door test in Oaklyn borough, NJ supports energy efficiency and verifies that your home meets local codes.

Homeowners who choose blower door test in Oaklyn borough, NJ can easily locate leaks. As the fan depressurizes the home, airflow through gaps becomes apparent, exposing areas needing improvement. It only takes a few hours to perform a blower door test, but the long-lasting impact on comfort and efficiency is felt through NJ’ hot summers and cool winters.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an air barrier like Tyvek or Zip Sheathing, making sure all connecting seams are properly taped and sealed.
Place insulation with the accurate R-value and check for proper installation and full coverage in the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close and seal every opening between heated or cooled spaces and unconditioned areas such as basements, attics, and crawl spaces.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.
Local Energy Audits technicians carry thermal imaging devices, caulk, and spray foam to pinpoint and seal air leaks immediately./li>

Preparing for a Blower Door Test in Oaklyn borough, NJ

Before conducting blower door test in Oaklyn borough, NJ, we make sure all heating, cooling, and ventilation fans are switched off. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Oaklyn borough, NJ.
