What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Harrison township (Gloucester), NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Harrison township (Gloucester), NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Harrison township (Gloucester), NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Passing this threshold during your blower door test in Harrison township (Gloucester), NJ ensures both energy savings and full compliance with local regulations.

Why Do I Need A Blower Door Test?

Homeowners experience real energy benefits from blower door test in Harrison township (Gloucester), NJ.

Preparing for a Blower Door Test in Harrison township (Gloucester), NJ

To properly prepare for blower door test in Harrison township (Gloucester), NJ, the HVAC system and all bathroom and kitchen fans are turned off. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Harrison township (Gloucester), NJ.
