What Is A Blower Door Test?

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 changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Lyndhurst, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. 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.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

Preparing for a Blower Door Test in Lyndhurst, NJ

Before starting blower door test in Lyndhurst, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Lyndhurst, NJ.
