What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in West Caldwell, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in West Caldwell, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. 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?

Homes in West Caldwell, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. When your blower door test in West Caldwell, NJmeets this requirement, you benefit from reduced energy bills and code compliance.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use Tyvek or Zip Sheathing as your air barrier and carefully tape all seams to prevent air leakage.
Install insulation that meets the required R-value and check that it’s evenly and securely placed throughout 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.
Ensure all penetrations between conditioned and unconditioned areas—like attics, basements, and crawl spaces—are tightly sealed.

Preparing for a Blower Door Test in West Caldwell, NJ

We begin blower door test in West Caldwell, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. 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 carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in West Caldwell, NJ.
