What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Oley, PA helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Oley, PA, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

In Oley, PA, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. 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 Oley, PAmeets this requirement, you benefit from reduced energy bills and code compliance.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal cracks and openings between conditioned interiors and unconditioned areas such as crawl spaces, attics, and basements.

Preparing for a Blower Door Test in Oley, PA

As part of preparing for blower door test in Oley, PA, we power down the HVAC system along with kitchen and bathroom exhaust fans. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Oley, PA energy code requirements.
