Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Rocky Hill, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

Preparing for a Blower Door Test in Rocky Hill, NJ

We start the process of blower door test in Rocky Hill, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or 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. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Rocky Hill, NJ.
