What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Sayreville, 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?

For accurate blower door test in Sayreville, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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 extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. 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?

In Sayreville, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. By meeting this standard in your blower door test in Sayreville, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Preparing for a Blower Door Test in Sayreville, NJ

Preparation for blower door test in Sayreville, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. 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. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Sayreville, NJ energy standards.
