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 changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Aston, PA helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Aston, PA, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

In Aston, PA, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Achieving this goal during your blower door test in Aston, PA promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Aston, PA

We begin blower door test in Aston, PA by switching off the HVAC system and shutting down all exhaust fans throughout the home. 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 sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Aston, PA.
