Blower Door Test in Haddon Heights, NJ

How Is A Blower Door Test Conducted?

When conducting blower door test in Haddon Heights, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

In Haddon Heights, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Reaching the target during your blower door test in Haddon Heights, NJ guarantees lower energy consumption and full code compliance.

How To Pass A Blower Door Test:

• Anticipate potential air leaks before testing begins.
• Install a quality air barrier like Tyvek or Zip Sheathing and confirm that all joints and seams are completely taped.
• Use properly rated insulation with the right R-value and ensure consistent coverage throughout 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.
• Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.
• Building departments in many areas share checklists for verifying compliance — download the Philadelphia version here as a sample.
• Using thermal imaging technology along with caulk and spray foam, Local Energy Audits identifies and seals leaks during the inspection./li>
