Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Lodi, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Lodi, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. 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 Lodi, NJ

To prepare a home for blower door test in Lodi, NJ, we shut off the HVAC system and disable all exhaust fans. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Lodi, NJ efficiency codes.
