What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Lower township, 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. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

Preparing for a Blower Door Test in Lower township, NJ

To ensure accuracy during blower door test in Lower township, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Lower township, NJ efficiency codes.
