What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Tabernacle township, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

Preparing for a Blower Door Test in Tabernacle township, NJ

To prepare a home for blower door test in Tabernacle township, NJ, we shut off the HVAC system and disable all exhaust fans. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Tabernacle township, NJ energy code requirements.
