What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Haledon, NJ allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Haledon, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

In Haledon, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Meeting this requirement during your blower door test in Haledon, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Why Do I Need A Blower Door Test?

Homeowners who choose blower door test in Haledon, NJ can easily locate leaks. As the fan depressurizes the home, airflow through gaps becomes apparent, exposing areas needing improvement. Though a blower door test lasts just a few hours, it offers a long-lasting impact on your home’s comfort, durability, and performance year-round in NJ.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Employ an appropriate air barrier system such as Tyvek or Zip Sheathing and verify that each seam has been correctly taped.
Install insulation with the appropriate R-value and ensure it is correctly fitted across the entire 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 all joints and gaps that connect conditioned and unconditioned areas such as basements, attics, and crawl spaces.
Building departments in many areas share checklists for verifying compliance — download the Philadelphia version here as a sample.
Equipped with thermal imaging tools, caulk, and spray foam, Local Energy Audits can find and fix leaks directly at your property./li>

Preparing for a Blower Door Test in Haledon, NJ

To properly prepare for blower door test in Haledon, NJ, the HVAC system and all bathroom and kitchen fans are turned off. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Haledon, NJ.
