What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Ventnor city, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Ventnor city, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance.

Preparing for a Blower Door Test in Ventnor city, NJ

For blower door test in Ventnor city, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. 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. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. 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 the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Ventnor city, NJ energy code requirements.
