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 frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Scotch Plains, 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?

To execute blower door test in Scotch Plains, 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. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

In Scotch Plains, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. When your blower door test in Scotch Plains, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Preparing for a Blower Door Test in Scotch Plains, NJ

Before conducting blower door test in Scotch Plains, NJ, we make sure all heating, cooling, and ventilation fans are switched off. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside 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. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Scotch Plains, NJ.
