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 too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Solebury, PA detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Solebury, PA, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. 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 air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. 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 Solebury, PA, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Achieving this goal during your blower door test in Solebury, PA promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Solebury, PA

We start the process of blower door test in Solebury, PA by ensuring all heating, air conditioning, and exhaust systems are turned off. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Solebury, PA.
