Blower Door Test in Elmwood Park, NJ

Test your home’s air barriers and meet energy regulations through dependable blower door test in Elmwood Park, 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 evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Elmwood Park, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Elmwood Park, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

In Elmwood Park, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Meeting this level during your blower door test in Elmwood Park, NJ supports energy efficiency and verifies that your home meets local codes.

Why Do I Need A Blower Door Test?

The State of NJ and numerous local municipalities adhere to the IECC (International Energy Conservation Code), which mandates blower door test for all newly built or renovated residential homes.

Homeowners who choose blower door test in Elmwood Park, NJ can easily locate leaks. As the fan depressurizes the home, airflow through gaps becomes apparent, exposing areas needing improvement. A blower door test requires minimal time but makes a long-lasting impact on home comfort and energy performance during NJ’ extreme temperatures.

How To Pass A Blower Door Test:

  • Anticipate potential air leaks before testing begins.
  • Use materials like Tyvek or Zip Sheathing as your air barrier and ensure every seam is well taped for best results.
  • Install insulation with the appropriate R-value and ensure it is correctly fitted across the entire 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 every transition point between conditioned and unconditioned environments, including attics, crawl spaces, and basements.

Preparing for a Blower Door Test in Elmwood Park, NJ

Preparation for blower door test in Elmwood Park, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond 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. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues 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 Elmwood Park, NJ.
