What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Audubon Park, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Audubon Park, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

In Audubon Park, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Complying with this benchmark during a blower door test in Audubon Park, NJ helps cut energy expenses and meet local building regulations.

Why Do I Need A Blower Door Test?

Homeowners experience real energy benefits from blower door test in Audubon Park, NJ. The fan’s depressurization highlights air leaks, helping identify inefficiencies that can be sealed for savings. Taking only a few hours, a blower door test creates a long-lasting impact by improving comfort, performance, and efficiency in NJhomes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
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.
Make sure to seal all separations between conditioned and unconditioned areas, including crawl spaces, basements, and attics.
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>
In the majority of cases—over 90%—we reach a passing score within two hours and provide all closing documentation.

Preparing for a Blower Door Test in Audubon Park, NJ

To prepare for blower door test in Audubon Park, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Audubon Park, NJ.

Blower Door Test for Contractors in Audubon Park, NJ

Contractors scheduling blower door test in Audubon Park, NJ often see that homes with proper insulation can correct minor air leaks while testing is underway. By applying materials such as chalk and spray foam, small leaks or gaps are often sealed on the spot.
