What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Plainsboro, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Plainsboro, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Plainsboro, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. By meeting this standard in your blower door test in Plainsboro, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Why Do I Need A Blower Door Test?

Use properly rated insulation with the right R-value and ensure consistent coverage throughout the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal all joints and gaps that connect conditioned and unconditioned areas such as basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Plainsboro, NJ

Preparation for blower door test in Plainsboro, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside the thermal envelope. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. 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. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Plainsboro, NJ.
