What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Linden, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Linden, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

Preparing for a Blower Door Test in Linden, NJ

Preparation for blower door test in Linden, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. 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. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. 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. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Linden, NJ.
