What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. 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 much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Gloucester Heights, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Gloucester Heights, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. 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 Gloucester Heights, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions.

Preparing for a Blower Door Test in Gloucester Heights, NJ

For blower door test in Gloucester Heights, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or 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. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Gloucester Heights, NJ energy standards.
