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. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Richboro, PA locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Richboro, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in PA.

What Is A Passing Blower Door Test Score?

In Richboro, PA, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Reaching this target in your blower door test in Richboro, PA helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Richboro, PA

To prepare for blower door test in Richboro, PA, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond 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 depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Richboro, PA.
