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. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Plainfield, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Plainfield, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

In Plainfield, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. When your blower door test in Plainfield, NJmeets this requirement, you benefit from reduced energy bills and code compliance.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Choose Tyvek or Zip Sheathing as your air barrier and check that all seams are securely taped to maintain airtightness.
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.
Close any gaps connecting conditioned and unconditioned spaces, such as those leading to basements, attics, or crawl spaces.
Building departments in many areas share checklists for verifying compliance — download the Philadelphia version here as a sample.
At Local Energy Audits, we utilize thermal imaging equipment, caulk, and spray foam to identify and fix air leaks during testing./li>

Preparing for a Blower Door Test in Plainfield, NJ

Before conducting blower door test in Plainfield, NJ, we make sure all heating, cooling, and ventilation fans are switched off. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Plainfield, NJ.
