What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Blackwood, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Blackwood, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

Homes built in Blackwood, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Meeting this benchmark in your blower door test in Blackwood, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Why Do I Need A Blower Door Test?

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use an air barrier system such as Tyvek or Zip Sheathing and verify that each seam is properly sealed with tape.
Use insulation of the correct R-value and confirm that it’s tightly installed throughout every section of 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.
Seal cracks and openings between conditioned interiors and unconditioned areas such as crawl spaces, attics, and basements.
Local code departments usually provide a checklist to assist with compliance — see the Philadelphia example here.
With the help of thermal imaging tools, caulk, and spray foam, Local Energy Audits efficiently detects and seals leaks on-site./li>

Preparing for a Blower Door Test in Blackwood, NJ

Before starting blower door test in Blackwood, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems 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 Blackwood, NJ efficiency standards.

Blower Door Test for Contractors in Blackwood, NJ
