What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Richboro, PA helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Richboro, PA, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. 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?

Houses in Richboro, PA are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance.

Preparing for a Blower Door Test in Richboro, PA

To prepare for blower door test in Richboro, PA, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. 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 Richboro, PA.
