What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Middle 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?

In preparation for blower door test in Middle township, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Houses in Middle township, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Complying with this benchmark during a blower door test in Middle township, NJ helps cut energy expenses and meet local building regulations.

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.
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.
Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.
Many cities provide compliance checklists through their building departments — see the Philadelphia version here.

Preparing for a Blower Door Test in Middle township, NJ

When preparing for blower door test in Middle township, 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. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering 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. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Middle township, NJ.
