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. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Worcester, PA detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Worcester, PA, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

What Is A Passing Blower Door Test Score?

Homes in Worcester, PA are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Reaching this target in your blower door test in Worcester, PA helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Worcester, PA

Preparation for blower door test in Worcester, PA includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. 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. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. 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 all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Worcester, PA energy standards.
