What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Lavallette borough, NJ allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Lavallette borough, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior 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?

In Lavallette borough, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Passing this threshold during your blower door test in Lavallette borough, NJ ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Lavallette borough, NJ

To properly prepare for blower door test in Lavallette borough, NJ, the HVAC system and all bathroom and kitchen fans are turned off. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing 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 completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Lavallette borough, NJ.
