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. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Monroe township (Gloucester), NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Monroe township (Gloucester), NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. 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. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

Houses in Monroe township (Gloucester), NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version.

Anticipate potential air leaks before testing begins.
Choose Tyvek or Zip Sheathing as your air barrier and check that all seams are securely taped to maintain airtightness.
Use insulation that has the designated R-value and confirm it’s properly applied throughout the building envelope for maximum efficiency.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close and seal every opening between heated or cooled spaces and unconditioned areas such as basements, attics, and crawl spaces.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.
With the help of thermal imaging tools, caulk, and spray foam, Local Energy Audits efficiently detects and seals leaks on-site./li>

Preparing for a Blower Door Test in Monroe township (Gloucester), NJ

To prepare for blower door test in Monroe township (Gloucester), NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Monroe township (Gloucester), NJ building codes.
