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. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. 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 Middle, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Middle, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural 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?

Houses in Middle, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. When your blower door test in Middle, NJmeets this requirement, you benefit from reduced energy bills and code compliance.

Preparing for a Blower Door Test in Middle, NJ

We start the process of blower door test in Middle, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. 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 the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Middle, NJ efficiency standards.
