Blower Door Test in Walpack Township, NJ

Detect hidden air leaks and improve efficiency with professional blower door test in Walpack Township, NJ. Our licensed professionals help homeowners, builders, and contractors identify air leaks, enhance comfort, and achieve NJ energy compliance.

What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. 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. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Walpack Township, 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?

While performing blower door test in Walpack Township, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. 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 the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

In Walpack Township, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Achieving this goal during your blower door test in Walpack Township, NJ promotes energy savings and demonstrates adherence to local building rules.

Why Do I Need A Blower Door Test?

NJ, along with many city governments, enforces the IECC, which requires blower door test for residential projects after construction or renovation. We regularly provide blower door test in Walpack Township, NJ for home builders, contractors, and homeowners working to meet local code requirements and close permits. A duct leakage test can be required when ducts or HVAC components are installed outside the structure’s thermal envelope. Learn more about energy code compliance.

Homeowners who choose blower door test in Walpack Township, NJ can easily locate leaks. As the fan depressurizes the home, airflow through gaps becomes apparent, exposing areas needing improvement. 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.
Choose an appropriate air barrier, like Tyvek or Zip Sheathing, and ensure all seams are accurately and securely taped.
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.
Eliminate air leaks by sealing all openings between conditioned areas and unconditioned spaces, including basements and attics.
Many building departments provide step-by-step compliance guides — you can find the Philadelphia example here.
Local Energy Audits is equipped with thermal imaging tools, caulk, and spray foam to find and seal air leaks immediately on-site./li>

Preparing for a Blower Door Test in Walpack Township, NJ

We start the process of blower door test in Walpack Township, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. 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. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Walpack Township, NJ.
