What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Saint Georges, DE, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior 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.

Preparing for a Blower Door Test in Saint Georges, DE

We start the process of blower door test in Saint Georges, DE by ensuring all heating, air conditioning, and exhaust systems are turned off. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Saint Georges, DE.
