What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in East Orange, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in East Orange, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air 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?

In East Orange, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Reaching the target during your blower door test in East Orange, NJ guarantees lower energy consumption and full code compliance.

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. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away.
