Ensure your property meets energy codes and maintains efficiency through expert blower door test in Clifton, 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 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 ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Clifton, 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?

When conducting blower door test in Clifton, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air 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 Clifton, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Complying with this benchmark during a blower door test in Clifton, NJ helps cut energy expenses and meet local building regulations.

Why Do I Need A Blower Door Test?

Following the IECC guidelines, NJ and many local jurisdictions require blower door test on newly built or renovated residential dwellings. We provide support to home builders, contractors, and homeowners needing blower door test in Clifton, NJ for meeting energy efficiency standards and finalizing permits. A duct leakage test may also be necessary if any ducts or HVAC systems are positioned outside the building’s thermal envelope. Learn more about energy code compliance.

Homeowners benefit from blower door test in Clifton, NJ because depressurization exposes airflow through cracks, helping identify leaks and boost efficiency. Typically completed within a few hours, a blower door test provides a long-lasting impact on comfort, energy efficiency, and overall home performance in NJ’ varied climate.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Choose an appropriate air barrier, like Tyvek or Zip Sheathing, and ensure all seams are accurately and securely taped.
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.
Eliminate air leaks by sealing all openings between conditioned areas and unconditioned spaces, including basements and attics.
Local building departments often supply a detailed checklist to ensure compliance — you can download the Philadelphia example here for guidance.
Local Energy Audits uses professional-grade thermal imaging, caulk, and spray foam to locate and close leaks during the visit./li>

Preparing for a Blower Door Test in Clifton, NJ

We start the process of blower door test in Clifton, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Clifton, NJ efficiency codes.
