What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Macungie, PA identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Macungie, PA, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in PA.

What Is A Passing Blower Door Test Score?

In Macungie, PA, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Achieving this goal during your blower door test in Macungie, PA promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Macungie, PA

We begin blower door test in Macungie, PA by switching off the HVAC system and shutting down all exhaust fans throughout the home. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Macungie, PA efficiency standards.
