What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Cherry Hill township, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

In Cherry Hill township, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency.

Preparing for a Blower Door Test in Cherry Hill township, NJ

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. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Cherry Hill township, NJ building codes.
