What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Chesterfield township, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Chesterfield township, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. 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 Chesterfield township, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. By meeting this standard in your blower door test in Chesterfield township, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Preparing for a Blower Door Test in Chesterfield township, NJ

To ensure accuracy during blower door test in Chesterfield township, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Chesterfield township, NJ.
