What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Bordentown city, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test.

Preparing for a Blower Door Test in Bordentown city, NJ

Preparation for blower door test in Bordentown city, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas 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 home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Bordentown city, NJ efficiency standards.
