What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Walpack Township, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Walpack Township, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

Preparing for a Blower Door Test in Walpack Township, NJ

For blower door test in Walpack Township, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Walpack Township, NJ.
