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. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Bethany Beach, 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?

For blower door test in Bethany Beach, DE, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the DE climate.

What Is A Passing Blower Door Test Score?

Houses in Bethany Beach, DE are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. When your blower door test in Bethany Beach, DE meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Preparing for a Blower Door Test in Bethany Beach, DE

To prepare a home for blower door test in Bethany Beach, DE, we shut off the HVAC system and disable all exhaust fans. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. 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 Bethany Beach, DE.
