Blower Door Test in Winslow, NJ

Assess your home’s air sealing and energy standards with trusted blower door test in Winslow, 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 checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. 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 Winslow, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Winslow, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Winslow, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. 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 Winslow, NJ helps cut energy expenses and meet local building regulations.

Why Do I Need A Blower Door Test?

Across NJ, the IECC (International Energy Conservation Code) is adopted by the state and local jurisdictions, requiring blower door test on residential constructions and renovations. We routinely help home builders, contractors, and homeowners requiring blower door test in Winslow, NJ for energy code compliance and permit closure. You may be required to perform a duct leakage test if HVAC components are situated outside the home’s thermal envelope. Learn more about energy code compliance.

There are many benefits of blower door test in Winslow, NJ for homeowners. When the fan lowers indoor pressure, leaks become visible, allowing for easy identification of inefficiencies and energy-saving opportunities. A short blower door test can result in a long-lasting impact on your home’s energy efficiency, comfort, and year-round performance in NJ.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an air barrier like Tyvek or Zip Sheathing, making sure all connecting seams are properly taped and sealed.
Apply insulation of the correct R-value and make sure it fits snugly in all areas of 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.
Seal cracks and openings between conditioned interiors and unconditioned areas such as crawl spaces, attics, and basements.
Many local municipalities issue code compliance checklists — the Philadelphia example is available here.
Local Energy Audits uses thermal imaging tools, caulk, and spray foam to detect and seal leaks directly on-site./li>
More than 90% of the time, we deliver a passing score in under two hours and issue all documents needed for permit approval.

Preparing for a Blower Door Test in Winslow, NJ

To ensure accuracy during blower door test in Winslow, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Winslow, NJ.
