Protect your energy investment and verify airtightness with advanced blower door test in Maple Shade township, NJ. Our skilled technicians help homeowners, builders, and contractors find air leaks, increase comfort, and comply with NJ energy standards.

What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Maple Shade township, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Maple Shade township, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. 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.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

Houses in Maple Shade township, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Satisfying this requirement in your blower door test in Maple Shade township, NJ helps optimize energy use and ensures you meet local building standards.

Why Do I Need A Blower Door Test?

The State of NJ, along with its municipalities, observes the IECC requirements, mandating blower door test for newly constructed or updated homes. We proudly serve home builders, contractors, and homeowners who need blower door test in Maple Shade township, NJ to pass inspections and fulfill energy code obligations. A duct leakage test could be required when air ducts or HVAC units extend outside the structure’s thermal envelope. Learn more about energy code compliance.

Homeowners benefit from blower door test in Maple Shade township, NJ because depressurization exposes airflow through cracks, helping identify leaks and boost efficiency. A blower door test, typically lasting only a few hours, offers a long-lasting impact on your home’s performance, efficiency, and comfort across NJ’ seasons.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use materials like Tyvek or Zip Sheathing as your air barrier and ensure every seam is well taped for best results.
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.
Properly seal all connections between conditioned and unconditioned zones, including basements, crawl spaces, and attics.
Many cities provide compliance checklists through their building departments — see the Philadelphia version here.
Using thermal imaging technology along with caulk and spray foam, Local Energy Audits identifies and seals leaks during the inspection./li>
More than 90% of our tests result in a passing score within two hours, along with immediate permit documentation.

Preparing for a Blower Door Test in Maple Shade township, NJ

Getting ready for blower door test in Maple Shade township, NJ involves turning off all heating, cooling, and exhaust ventilation systems. 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 from outside rushes in through cracks and gaps, making leak detection much easier. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Maple Shade township, NJ.

Blower Door Test for Contractors in Maple Shade township, NJ

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