Achieve peak energy efficiency and verify airtight construction with professional blower door test in Weehawken, NJ. Our skilled technicians help homeowners, builders, and contractors find air leaks, increase comfort, and comply with NJ energy standards.

What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. 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 Weehawken, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Weehawken, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. 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?

Properties in Weehawken, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Meeting this level during your blower door test in Weehawken, NJ supports energy efficiency and verifies that your home meets local codes.

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.
Apply insulation of the correct R-value and make sure it fits snugly in all areas 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.
Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.
Local building departments often supply a detailed checklist to ensure compliance — you can download the Philadelphia example here for guidance.
Local Energy Audits brings thermal cameras, caulk, and spray foam to locate and seal leaks while performing on-site testing./li>

Preparing for a Blower Door Test in Weehawken, NJ

As part of preparing for blower door test in Weehawken, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. 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 airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. 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 Weehawken, NJ.
