Confirm your home’s energy performance and identify leaks through accurate blower door test in Willingboro, NJ. Our certified team helps homeowners, builders, and contractors locate air leaks, enhance indoor comfort, and meet all NJ energy efficiency requirements.

What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Willingboro, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Willingboro, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Willingboro, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Reaching this target in your blower door test in Willingboro, NJ helps maintain lower energy bills and fulfills local code obligations.

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 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.
Ensure complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.
Many cities provide compliance checklists through their building departments — see the Philadelphia version here.
Local Energy Audits provides on-site leak detection and sealing using advanced thermal imaging tools, caulk, and spray foam./li>
Typically, over 90% of the time we record a passing score in two hours and handle all permit-related documentation.

Preparing for a Blower Door Test in Willingboro, NJ

To prepare for blower door test in Willingboro, 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. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Willingboro, NJ efficiency standards.
