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. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Margate City, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Margate City, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Margate City, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Meeting this level during your blower door test in Margate City, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Margate City, NJ

To get ready for blower door test in Margate City, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Margate City, NJ energy code requirements.
