Verify your home’s airtightness and meet energy-efficiency standards with a professional blower door test in Park Ridge, 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 measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Park Ridge, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Park Ridge, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. 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?

Homes built in Park Ridge, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Meeting this level during your blower door test in Park Ridge, NJ supports energy efficiency and verifies that your home meets local codes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Install a quality air barrier like Tyvek or Zip Sheathing and confirm that all joints and seams are completely taped.
Fit insulation with the correct R-value and make sure it’s installed without voids 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.
Ensure all penetrations between conditioned and unconditioned areas—like attics, basements, and crawl spaces—are tightly sealed.
Local code departments usually provide a checklist to assist with compliance — see the Philadelphia example here.
Local Energy Audits brings thermal cameras, caulk, and spray foam to locate and seal leaks while performing on-site testing./li>

Preparing for a Blower Door Test in Park Ridge, NJ

Before starting blower door test in Park Ridge, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near 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. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Park Ridge, NJ.
