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. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. 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 Furlong, PA 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?

While performing blower door test in Furlong, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the PA environment.

What Is A Passing Blower Door Test Score?

Residential buildings in Furlong, PA must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Complying with this benchmark during a blower door test in Furlong, PA helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Furlong, PA

To prepare a home for blower door test in Furlong, PA, we shut off the HVAC system and disable all exhaust fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Furlong, PA building codes.
