What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh 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 Blades, DE makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Blades, DE, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in DE conditions.

What Is A Passing Blower Door Test Score?

Homes throughout Blades, DE are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Meeting this requirement during your blower door test in Blades, DE helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Blades, DE

Before starting blower door test in Blades, DE, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Blades, DE.
