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. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Franklin 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?

During blower door test in Franklin township, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

In Franklin township, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions.

Preparing for a Blower Door Test in Franklin township, NJ

When preparing for blower door test in Franklin township, NJ, we first switch off the home’s heating, cooling, and exhaust systems. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Franklin township, NJ.
