What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. 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 can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Pequannock, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Pequannock, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

Homes in Pequannock, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Meeting this requirement during your blower door test in Pequannock, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Pequannock, NJ

For blower door test in Pequannock, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Pequannock, NJ.
