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. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Plymouth Meeting, 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 execute blower door test in Plymouth Meeting, PA, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural 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 Plymouth Meeting, PA, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction.

Preparing for a Blower Door Test in Plymouth Meeting, PA

Preparation for blower door test in Plymouth Meeting, PA begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to 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 the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Plymouth Meeting, PA.
