What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. 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. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Metuchen, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Metuchen, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. 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 air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Metuchen, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency.

Preparing for a Blower Door Test in Metuchen, NJ

To ensure accuracy during blower door test in Metuchen, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. 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 doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Metuchen, NJ.
