What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Fairless Hills, PA helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Fairless Hills, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

In Fairless Hills, PA, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency.

Preparing for a Blower Door Test in Fairless Hills, PA

To prepare for blower door test in Fairless Hills, 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. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected 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. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Fairless Hills, PA building codes.
