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. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Pennsburg, PA helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Pennsburg, PA, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

In Pennsburg, PA, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close and seal every opening between heated or cooled spaces and unconditioned areas such as basements, attics, and crawl spaces.
Local code offices often issue compliance checklists — access the Philadelphia example here for reference.

Preparing for a Blower Door Test in Pennsburg, PA

We begin blower door test in Pennsburg, PA by switching off the HVAC system and shutting down all exhaust fans throughout the home. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Pennsburg, PA energy code requirements.
