What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Egg Harbor city, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Egg Harbor city, 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 is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

In Egg Harbor city, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes.

Preparing for a Blower Door Test in Egg Harbor city, NJ

We start the process of blower door test in Egg Harbor city, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. 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. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Egg Harbor city, NJ.
