What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. 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 Middletown, NJ 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?

Before blower door test in Middletown, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

In Middletown, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Satisfying this requirement in your blower door test in Middletown, NJ helps optimize energy use and ensures you meet local building standards.

Anticipate potential air leaks before testing begins.
Apply an effective air barrier such as Tyvek or Zip Sheathing, ensuring every seam is tightly sealed with proper tape.
Install insulation of the appropriate R-value and inspect to confirm it’s correctly fitted in all envelope areas.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Properly seal all connections between conditioned and unconditioned zones, including basements, crawl spaces, and attics.

Preparing for a Blower Door Test in Middletown, NJ

Preparation for blower door test in Middletown, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Middletown, NJ.
