What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Woodland Park, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Woodland Park, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Woodland Park, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Achieving this goal during your blower door test in Woodland Park, NJ promotes energy savings and demonstrates adherence to local building rules.

Why Do I Need A Blower Door Test?

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Choose Tyvek or Zip Sheathing as your air barrier and check that all seams are securely taped to maintain airtightness.
Ensure the insulation used meets the proper R-value and is well fitted throughout the structure’s 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 complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.
Building departments in many areas share checklists for verifying compliance — download the Philadelphia version here as a sample.

Preparing for a Blower Door Test in Woodland Park, NJ

Preparation for blower door test in Woodland Park, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Woodland Park, NJ.
