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. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in East Windsor, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in East Windsor, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Residential buildings in East Windsor, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations.

Preparing for a Blower Door Test in East Windsor, NJ

When preparing for blower door test in East Windsor, NJ, we first switch off the home’s heating, cooling, and exhaust systems. 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. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with East Windsor, NJ energy standards.
