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 exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Byram, 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?

For accurate blower door test in Byram, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Homes in Byram, 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. Complying with this benchmark during a blower door test in Byram, NJ helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Byram, NJ

Before starting blower door test in Byram, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Byram, NJ energy code requirements.
