What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Bergenfield, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Bergenfield, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

In Bergenfield, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Reaching this target in your blower door test in Bergenfield, NJ helps maintain lower energy bills and fulfills local code obligations.

  • Select a proper air barrier such as Tyvek or Zip Sheathing and ensure every seam is thoroughly taped for airtight sealing.
  • Use insulation that has the designated R-value and confirm it’s properly applied throughout the building envelope for maximum efficiency.
  • Seal all penetrations in exterior walls using caulk or spray foam.
  • Ensure doors and windows are properly installed, caulked, and weather-sealed.
  • Seal all openings between conditioned and unconditioned areas, including basements, attics, and crawl spaces.
  • Local code offices often issue compliance checklists — access the Philadelphia example here for reference.

Preparing for a Blower Door Test in Bergenfield, NJ

To prepare for blower door test in Bergenfield, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond 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. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. 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 completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Bergenfield, NJ efficiency standards.
