A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Freehold township, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Freehold township, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

Houses in Freehold township, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Reaching this target in your blower door test in Freehold township, NJ helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Freehold township, NJ

To properly prepare for blower door test in Freehold township, NJ, the HVAC system and all bathroom and kitchen fans are turned off. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside 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. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into 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. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Freehold township, NJ.
