What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Mancheste r township, 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?

To execute blower door test in Mancheste r township, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

Houses in Mancheste r township, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version.

Preparing for a Blower Door Test in Mancheste r township, NJ

We begin blower door test in Mancheste r township, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. 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. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent 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 sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Mancheste r township, NJ.
