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. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Ocean View, DE assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Ocean View, DE, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in DE conditions.

What Is A Passing Blower Door Test Score?

In Ocean View, DE, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. When your blower door test in Ocean View, DE meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Ocean View, DE

Before starting blower door test in Ocean View, DE, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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 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. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected 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 completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Ocean View, DE.
