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. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Wayne, PA assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Wayne, PA, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in PA weather.

What Is A Passing Blower Door Test Score?

In Wayne, PA, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. When your blower door test in Wayne, PA meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Ensure the insulation used meets the proper R-value and is well fitted throughout the structure’s building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.

Preparing for a Blower Door Test in Wayne, PA

Preparation for blower door test in Wayne, PA begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to 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. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Wayne, PA.
