What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Rehoboth Beach, DE detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Rehoboth Beach, DE, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in DE climates.

What Is A Passing Blower Door Test Score?

In Rehoboth Beach, DE, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. 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 requirement during your blower door test in Rehoboth Beach, DE helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Rehoboth Beach, DE

Before starting blower door test in Rehoboth Beach, DE, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve 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. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Rehoboth Beach, DE.
