What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Upper Saddle River, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Upper Saddle River, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

Residential buildings in Upper Saddle River, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. Reaching the target during your blower door test in Upper Saddle River, NJ guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Upper Saddle River, NJ

We start the process of blower door test in Upper Saddle River, NJ by ensuring all heating, air conditioning, and exhaust systems 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. 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. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Upper Saddle River, NJ energy efficiency codes.
