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. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Pike Creek Valley, 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?

While performing blower door test in Pike Creek Valley, DE, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in DE.

What Is A Passing Blower Door Test Score?

In Pike Creek Valley, DE, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Meeting this level during your blower door test in Pike Creek Valley, DE supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Pike Creek Valley, DE

When preparing for blower door test in Pike Creek Valley, DE, we first switch off the home’s heating, cooling, and exhaust systems. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Pike Creek Valley, DE.
