What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Trumbauersville, PA, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of 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 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 Trumbauersville, 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 jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. When your blower door test in Trumbauersville, PA meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Preparing for a Blower Door Test in Trumbauersville, PA

To properly prepare for blower door test in Trumbauersville, PA, the HVAC system and all bathroom and kitchen fans are turned off. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Trumbauersville, PA.
