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. 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. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Union township, 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?

In blower door test in Union township, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. 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 expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

In Union township, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Reaching the target during your blower door test in Union township, NJ guarantees lower energy consumption and full code compliance.

Use a reliable air barrier like Tyvek or Zip Sheathing and make sure all seams are securely 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.
Ensure all penetrations between conditioned and unconditioned areas—like attics, basements, and crawl spaces—are tightly sealed.
Local building authorities commonly offer checklists to verify code compliance — review the Philadelphia example here.
With caulk, spray foam, and advanced thermal imaging, Local Energy Audits locates and seals leaks efficiently on-site./li>

Preparing for a Blower Door Test in Union township, NJ

Before starting blower door test in Union township, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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 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. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Union township, NJ.
