Blower Door Test in Edison, NJ

Protect your energy investment and verify airtightness with advanced blower door test in Edison, NJ. Our certified professionals work with homeowners, builders, and contractors to uncover hidden air leaks and guarantee compliance with NJ energy codes.

What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Edison, 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?

To execute blower door test in Edison, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for 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 pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. 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?

Residential buildings in Edison, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Reaching the target during your blower door test in Edison, NJ guarantees lower energy consumption and full code compliance.

Why Do I Need A Blower Door Test?

Both NJ and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures. We provide support to home builders, contractors, and homeowners needing blower door test in Edison, NJ for meeting energy efficiency standards and finalizing permits. A duct leakage test may also be performed when ductwork or HVAC equipment extends beyond the thermal envelope. Learn more about energy code compliance.

Homeowners benefit from blower door test in Edison, 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 high-quality air barrier materials like Tyvek or Zip Sheathing and confirm all seams are perfectly taped.
Install insulation with the appropriate R-value and ensure it is correctly fitted across the entire 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 all joints and gaps that connect conditioned and unconditioned areas such as basements, attics, and crawl spaces.
Local permitting offices often offer official compliance checklists — review the Philadelphia sample here for reference.
Our team at Local Energy Audits employs thermal imaging, caulk, and spray foam to locate and repair leaks efficiently on-site./li>
In more than 90% of cases, we secure a passing score within two hours and deliver the paperwork needed to close the permit.

Preparing for a Blower Door Test in Edison, NJ

To properly prepare for blower door test in Edison, NJ, the HVAC system and all bathroom and kitchen fans are turned off. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area 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. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. 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’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. 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 Edison, NJ.
