What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Paulsboro, 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?

While performing blower door test in Paulsboro, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. 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 exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. 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?

In Paulsboro, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. By meeting this standard in your blower door test in Paulsboro, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Preparing for a Blower Door Test in Paulsboro, NJ

When preparing for blower door test in Paulsboro, 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 sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Paulsboro, NJ.
