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. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Franklin Lakes, 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?

During blower door test in Franklin Lakes, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

In Franklin Lakes, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Achieving compliance in your blower door test in Franklin Lakes, NJ helps improve energy efficiency and meet all local code mandates.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use a reliable air barrier like Tyvek or Zip Sheathing and make sure all seams are securely taped.
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.
Make sure to seal all separations between conditioned and unconditioned areas, including crawl spaces, basements, and attics.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.

Preparing for a Blower Door Test in Franklin Lakes, NJ

When preparing for blower door test in Franklin Lakes, NJ, we first switch off the home’s heating, cooling, and exhaust systems. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Franklin Lakes, NJ energy standards.
