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. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Freehold borough, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Freehold borough, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Meeting this level during your blower door test in Freehold borough, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Freehold borough, NJ

Preparation for blower door test in Freehold borough, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to 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 completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Freehold borough, NJ efficiency standards.
