What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Gloucester township, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Gloucester township, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. 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?

Homes built in Gloucester township, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Passing this requirement during a blower door test in Gloucester township, NJ keeps your home efficient and aligned with local building code standards.

Why Do I Need A Blower Door Test?

The State of NJ, together with many cities and counties, enforces the IECC (International Energy Conservation Code), which calls for blower door test on new or renovated residential properties. Our company assists home builders, contractors, and homeowners who rely on blower door test in Gloucester township, NJ to fulfill energy code compliance and finalize construction permits.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Employ an appropriate air barrier system such as Tyvek or Zip Sheathing and verify that each seam has been correctly taped.
Install correctly rated insulation with the proper R-value and confirm it’s well positioned in every part of the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal off any access points or gaps between conditioned and unconditioned spaces like attics, crawl spaces, and basements.
Building departments typically release step-by-step compliance lists — download the Philadelphia sample here as an example.
Local Energy Audits provides on-site leak detection and sealing using advanced thermal imaging tools, caulk, and spray foam./li>
In the majority of cases—over 90%—we reach a passing score within two hours and provide all closing documentation.

Preparing for a Blower Door Test in Gloucester township, NJ

We start the process of blower door test in Gloucester 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. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing 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. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Gloucester township, NJ.
