What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Mount Laurel township, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Mount Laurel township, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. 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?

Construction in Mount Laurel township, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. When your blower door test in Mount Laurel township, NJmeets this requirement, you benefit from reduced energy bills and code compliance.

A blower door test is quick to perform but offers a long-lasting impact on comfort, energy savings, and home efficiency across all NJclimates.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an effective air barrier such as Tyvek or Zip Sheathing, ensuring every seam is tightly sealed with proper tape.
Install insulation of the appropriate R-value and inspect to confirm it’s correctly fitted in all envelope areas.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal cracks and openings between conditioned interiors and unconditioned areas such as crawl spaces, attics, and basements.
Many local municipalities issue code compliance checklists — the Philadelphia example is available here.
Using thermal imaging technology along with caulk and spray foam, Local Energy Audits identifies and seals leaks during the inspection./li>

Preparing for a Blower Door Test in Mount Laurel township, NJ

Getting ready for blower door test in Mount Laurel township, NJ involves turning off all heating, cooling, and exhaust ventilation systems. 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. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Mount Laurel township, NJ efficiency standards.
