What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Audubon Park, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Audubon Park, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. 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 extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

Homes built in Audubon Park, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. By meeting this standard in your blower door test in Audubon Park, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Use properly rated insulation with the right R-value and ensure consistent coverage throughout the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Ensure complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Audubon Park, NJ

To prepare for blower door test in Audubon Park, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. 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 carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Audubon Park, NJ.
