What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Gladwyne, PA allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Gladwyne, PA is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. 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 exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the PA climate.

What Is A Passing Blower Door Test Score?

In Gladwyne, PA, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. When your blower door test in Gladwyne, PAmeets this requirement, you benefit from reduced energy bills and code compliance.

Preparing for a Blower Door Test in Gladwyne, PA

To properly prepare for blower door test in Gladwyne, PA, the HVAC system and all bathroom and kitchen fans are turned off. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Gladwyne, PA.
