What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Woodbury Heights, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

What Is A Passing Blower Door Test Score?

In Woodbury Heights, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance.

Preparing for a Blower Door Test in Woodbury Heights, NJ

Before conducting blower door test in Woodbury Heights, NJ, we make sure all heating, cooling, and ventilation fans are switched off. 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 sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and 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. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Woodbury Heights, NJ energy standards.
