What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Ambler, PA identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Ambler, PA, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. 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.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in PA.

Reaching this target in your blower door test in Ambler, PA helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Ambler, PA

To properly prepare for blower door test in Ambler, PA, the HVAC system and all bathroom and kitchen fans are turned off. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. 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 Ambler, PA.
