What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in South Plainfield, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in South Plainfield, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. 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?

Residential buildings in South Plainfield, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. When your blower door test in South Plainfield, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Install a quality air barrier like Tyvek or Zip Sheathing and confirm that all joints and seams are completely taped.
Place insulation with the accurate R-value and check for proper installation and full coverage in 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 the transitions between conditioned and unconditioned zones, particularly around basements, attics, and crawl spaces.
Local building authorities commonly offer checklists to verify code compliance — review the Philadelphia example here.

Preparing for a Blower Door Test in South Plainfield, NJ

To ensure accuracy during blower door test in South Plainfield, 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. 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. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering 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 the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in South Plainfield, NJ.
