What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Medford Lakes, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Medford Lakes, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. 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 Medford Lakes, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Achieving this standard in your blower door test in Medford Lakes, NJ lowers utility bills and guarantees adherence to local code requirements.

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.
Apply the correct R-value insulation and verify that it’s properly fitted to seal the whole 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.
Building departments typically release step-by-step compliance lists — download the Philadelphia sample here as an example.
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 Medford Lakes, NJ

Before starting blower door test in Medford Lakes, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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 the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Medford Lakes, NJ.
