What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Eagleville, PA enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Eagleville, PA, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. 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.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. 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 Eagleville, PA, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. When your blower door test in Eagleville, PAmeets this requirement, you benefit from reduced energy bills and code compliance.

Preparing for a Blower Door Test in Eagleville, PA

Preparation for blower door test in Eagleville, PA includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond 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. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. 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 completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Eagleville, PA.
