What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Waldwick, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

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. 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?

Homes in Waldwick, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance.

Preparing for a Blower Door Test in Waldwick, NJ

Before conducting blower door test in Waldwick, NJ, we make sure all heating, cooling, and ventilation fans are switched off. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Waldwick, NJ energy efficiency codes.
