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. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced 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 Wycombe, 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 Wycombe, PA, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

Homes throughout Wycombe, PA are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level.

Preparing for a Blower Door Test in Wycombe, PA

When preparing for blower door test in Wycombe, PA, we first switch off the home’s heating, cooling, and exhaust systems. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into 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. 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 Wycombe, PA.
