What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in South River, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in South River, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

What Is A Passing Blower Door Test Score?

In South River, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. 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. Reaching this target in your blower door test in South River, NJ helps maintain lower energy bills and fulfills local code obligations.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use an air barrier system such as Tyvek or Zip Sheathing and verify that each seam is properly sealed with tape.
Ensure the insulation used meets the proper R-value and is well fitted throughout the structure’s building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close any gaps connecting conditioned and unconditioned spaces, such as those leading to basements, attics, or crawl spaces.
Many local municipalities issue code compliance checklists — the Philadelphia example is available here.
Using thermal imaging technology along with caulk and spray foam, Local Energy Audits identifies and seals leaks during the inspection./li>

Preparing for a Blower Door Test in South River, NJ

We start the process of blower door test in South River, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. 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. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in South River, NJ.
