What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Ventnor city, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Ventnor city, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

Residential buildings in Ventnor city, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. When your blower door test in Ventnor city, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Homeowners gain major advantages from blower door test in Ventnor city, NJ. As the fan depressurizes the home, incoming air through leaks becomes easier to detect, revealing problem spots and potential energy-saving improvements. Though a blower door test lasts just a few hours, it offers a long-lasting impact on your home’s comfort, durability, and performance year-round in NJ.

How To Pass A Blower Door Test:

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.

Preparing for a Blower Door Test in Ventnor city, NJ

We start the process of blower door test in Ventnor city, NJ by ensuring all heating, air conditioning, and exhaust systems 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. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Ventnor city, NJ.
