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. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Dumont, 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?

For blower door test in Dumont, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

Houses in Dumont, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Achieving this goal during your blower door test in Dumont, NJ promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Dumont, NJ

To get ready for blower door test in Dumont, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within 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. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining 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. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Dumont, NJ efficiency codes.
