What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. 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 Newton, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Newton, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. 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 starts pulling air out, external air enters through the smallest cracks and leakage points. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Newton, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. Achieving this standard in your blower door test in Newton, 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 air barrier like Tyvek or Zip Sheathing, making sure all connecting seams are properly taped and sealed.
Place insulation with the accurate R-value and check for proper installation and full coverage in 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.
Seal all openings between conditioned and unconditioned areas, including basements, attics, and crawl spaces.
Local code departments usually provide a checklist to assist with compliance — see the Philadelphia example here.
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 Newton, NJ

As part of preparing for blower door test in Newton, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. 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 Newton, NJ.

Most professionally insulated homes undergoing blower door test in Newton, NJ can resolve small issues on-site during the contractor’s visit.
