What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. 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 Audubon borough, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Audubon borough, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. 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.

Preparing for a Blower Door Test in Audubon borough, NJ

For blower door test in Audubon borough, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom 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 everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Audubon borough, NJ energy efficiency codes.
