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 ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Fountainville, PA finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Fountainville, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the PA climate.

What Is A Passing Blower Door Test Score?

In Fountainville, PA, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes 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 Fountainville, PA

Preparation for blower door test in Fountainville, PA begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside 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. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Fountainville, PA energy efficiency codes.
