What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Commercial, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Commercial, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

In Commercial, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Complying with this benchmark during a blower door test in Commercial, NJ helps cut energy expenses and meet local building regulations.

Why Do I Need A Blower Door Test?

The State of NJ and its local governments follow the IECC standards, which require blower door test on newly built or remodeled residential dwellings.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an appropriate air barrier, such as Tyvek or Zip Sheathing, making sure every seam is correctly taped for maximum performance.
Use insulation with the right R-value and confirm it is properly installed 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.
Seal gaps and openings separating conditioned spaces from unconditioned areas, including crawl spaces, basements, and attics.
Local jurisdictions frequently publish compliance checklists — the Philadelphia version can be downloaded here.

Preparing for a Blower Door Test in Commercial, NJ

To prepare a home for blower door test in Commercial, NJ, we shut off the HVAC system and disable all 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. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Commercial, NJ energy code requirements.
