What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Winslow, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Winslow, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Winslow, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Passing this requirement during a blower door test in Winslow, NJ keeps your home efficient and aligned with local building code standards.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.

Preparing for a Blower Door Test in Winslow, NJ

To properly prepare for blower door test in Winslow, NJ, the HVAC system and all bathroom and kitchen fans are turned off. 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. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. 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 completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Winslow, NJ efficiency standards.
