What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. 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 Essington, 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?

In blower door test in Essington, PA, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A sensitive device called a nanometer measures how the fan’s pressure relates 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.

Preparing for a Blower Door Test in Essington, PA

Before conducting blower door test in Essington, PA, we make sure all heating, cooling, and ventilation fans are switched 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. 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. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Essington, PA energy efficiency codes.
