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. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Westdeptford, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Westdeptford, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. 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?

In Westdeptford, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Satisfying this requirement in your blower door test in Westdeptford, NJ helps optimize energy use and ensures you meet local building standards.

Why Do I Need A Blower Door Test?

The State of NJ, along with its municipalities, observes the IECC requirements, mandating blower door test for newly constructed or updated homes.

How To Pass A Blower Door Test:

  • Anticipate potential air leaks before testing begins.
  • Use materials like Tyvek or Zip Sheathing as your air barrier and ensure every seam is well taped for best results.
  • 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.
  • Seal all joints and gaps that connect conditioned and unconditioned areas such as basements, attics, and crawl spaces.
  • Most building departments provide detailed compliance resources — view the Philadelphia checklist example here.
  • Local Energy Audits provides on-site leak detection and sealing using advanced thermal imaging tools, caulk, and spray foam./li>

Preparing for a Blower Door Test in Westdeptford, NJ

When preparing for blower door test in Westdeptford, NJ, we first switch off the home’s heating, cooling, and exhaust systems. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors 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 Westdeptford, NJ.
