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. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. 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 Linden, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Linden, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

In Linden, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Reaching this target in your blower door test in Linden, NJ helps maintain lower energy bills and fulfills local code obligations.

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 building authorities commonly offer checklists to verify code compliance — review the Philadelphia example here.
Local Energy Audits uses thermal imaging tools, caulk, and spray foam to detect and seal leaks directly on-site./li>

Preparing for a Blower Door Test in Linden, NJ

To properly prepare for blower door test in Linden, NJ, the HVAC system and all bathroom and kitchen fans are turned off. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Linden, NJ efficiency codes.

Blower Door Test for Contractors in Linden, NJ

For contractors conducting blower door test in Linden, NJ, well-insulated homes generally require only minimal on-site corrections during the test.
