What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Pike Creek, DE helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Pike Creek, DE, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the DE climate.

What Is A Passing Blower Door Test Score?

In Pike Creek, DE, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Achieving compliance in your blower door test in Pike Creek, DE helps improve energy efficiency and meet all local code mandates.

Preparing for a Blower Door Test in Pike Creek, DE

As part of preparing for blower door test in Pike Creek, DE, we power down the HVAC system along with kitchen and bathroom exhaust fans. 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. 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. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Pike Creek, DE energy code requirements.
