What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. 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 often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Morris Plains, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Morris Plains, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

Preparing for a Blower Door Test in Morris Plains, NJ

To get ready for blower door test in Morris Plains, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Morris Plains, NJ building codes.
