What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Chesterfield, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Chesterfield, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

Properties in Chesterfield, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Reaching the target during your blower door test in Chesterfield, NJ guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Chesterfield, NJ

Getting ready for blower door test in Chesterfield, NJ involves turning off all heating, cooling, and exhaust ventilation systems. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond 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. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Chesterfield, NJ energy standards.
