What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Manville, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Manville, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

Homes built in Manville, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Reaching the target during your blower door test in Manville, NJ guarantees lower energy consumption and full code compliance.

Why Do I Need A Blower Door Test?

How To Pass A Blower Door Test:

  • Anticipate potential air leaks before testing begins.
  • Apply an effective air barrier such as Tyvek or Zip Sheathing, ensuring every seam is tightly sealed with proper tape.
  • Ensure insulation with the specified R-value is properly installed and fitted throughout 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.
  • Close and seal every opening between heated or cooled spaces and unconditioned areas such as basements, attics, and crawl spaces.
  • Local building authorities commonly offer checklists to verify code compliance — review the Philadelphia example here.
  • Local Energy Audits technicians carry thermal imaging devices, caulk, and spray foam to pinpoint and seal air leaks immediately./li>

Preparing for a Blower Door Test in Manville, NJ

When preparing for blower door test in Manville, NJ, we first switch off the home’s heating, cooling, and exhaust systems. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Manville, NJ.
