What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Lawrence township, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

In Lawrence township, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Achieving compliance in your blower door test in Lawrence township, NJ helps improve energy efficiency and meet all local code mandates.

Preparing for a Blower Door Test in Lawrence township, NJ

We start the process of blower door test in Lawrence township, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Lawrence township, NJ energy code requirements.
