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. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Rising Sun-Lebanon, DE locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Rising Sun-Lebanon, DE, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. 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?

Houses in Rising Sun-Lebanon, DE are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Satisfying this requirement in your blower door test in Rising Sun-Lebanon, DE helps optimize energy use and ensures you meet local building standards.

Preparing for a Blower Door Test in Rising Sun-Lebanon, DE

When preparing for blower door test in Rising Sun-Lebanon, DE, we first switch off the home’s heating, cooling, and exhaust systems. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Rising Sun-Lebanon, DE.
