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. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. 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 Kinnelon, 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?

While performing blower door test in Kinnelon, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. 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.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

Homes throughout Kinnelon, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Satisfying this requirement in your blower door test in Kinnelon, NJ helps optimize energy use and ensures you meet local building standards.

Why Do I Need A Blower Door Test?

Homeowners see real value in blower door test in Kinnelon, NJ. As the fan draws air out, leaks become clear, making it easy to target repairs and improve efficiency. In only a few hours, a blower door test can deliver a long-lasting impact on energy efficiency, comfort, and indoor performance throughout NJ’ changing seasons.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Install an effective air barrier, for example Tyvek or Zip Sheathing, and make certain all seams are sealed with durable tape.
Use insulation featuring the proper R-value and verify complete, gap-free coverage across 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.
Building departments in many areas share checklists for verifying compliance — download the Philadelphia version here as a sample.
Our professionals at Local Energy Audits use caulk, spray foam, and thermal imaging to detect and seal leaks on-site for better efficiency./li>

Preparing for a Blower Door Test in Kinnelon, NJ

Preparation for blower door test in Kinnelon, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Kinnelon, NJ energy standards.

Blower Door Test for Contractors in Kinnelon, NJ

For contractors conducting blower door test in Kinnelon, NJ, well-insulated homes generally require only minimal on-site corrections during the test. With materials such as chalk and spray foam, most small leaks or gaps can be sealed immediately on-site. In more than 90% of cases, we achieve a passing blower door test score within two hours and provide complete documentation to close out the building permit the same day.
