What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Glendora, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Glendora, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. 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 Glendora, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Achieving this goal during your blower door test in Glendora, NJ promotes energy savings and demonstrates adherence to local building rules.

Why Do I Need A Blower Door Test?

NJ state regulations and many municipalities abide by the IECC, enforcing blower door tests for newly constructed or renovated homes. We often work with home builders, contractors, and homeowners requiring blower door test in Glendora, NJ to meet local energy codes and obtain permit approval.

Preparing for a Blower Door Test in Glendora, NJ

Before conducting blower door test in Glendora, NJ, we make sure all heating, cooling, and ventilation fans are switched off. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Glendora, NJ energy standards.
