What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Alburtis, PA detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Alburtis, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the PA climate.

What Is A Passing Blower Door Test Score?

In Alburtis, PA, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions.

Preparing for a Blower Door Test in Alburtis, PA

To prepare for blower door test in Alburtis, PA, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces 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. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Alburtis, PA energy efficiency codes.
