What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Rodney Village, DE identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Rodney Village, DE, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. 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 Rodney Village, DE, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Meeting this benchmark in your blower door test in Rodney Village, DE reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Rodney Village, DE

To properly prepare for blower door test in Rodney Village, DE, the HVAC system and all bathroom and kitchen fans are turned off. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. 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 Rodney Village, DE.
