What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Seaford, DE allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Seaford, DE, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in DE weather.

What Is A Passing Blower Door Test Score?

In Seaford, DE, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. By meeting this standard in your blower door test in Seaford, DE, you can enjoy lower utility bills and peace of mind with code compliance.

Preparing for a Blower Door Test in Seaford, DE

Getting ready for blower door test in Seaford, DE involves turning off all heating, cooling, and exhaust ventilation systems. 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 sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Seaford, DE.
