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. 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 Jersey City, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Jersey City, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. 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 indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

In Jersey City, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Passing this threshold during your blower door test in Jersey City, NJ ensures both energy savings and full compliance with local regulations.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use a trusted air barrier like Tyvek or Zip Sheathing, ensuring all joints and seams are properly taped and sealed.
Use insulation of the correct R-value and confirm that it’s tightly installed throughout every section 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.
Close and seal every opening between heated or cooled spaces 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.
Equipped with thermal imaging tools, caulk, and spray foam, Local Energy Audits can find and fix leaks directly at your property./li>

Preparing for a Blower Door Test in Jersey City, NJ

Preparation for blower door test in Jersey City, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside 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. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into 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. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Jersey City, NJ.
