What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Green Lane, PA enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Green Lane, PA, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in PA.

What Is A Passing Blower Door Test Score?

In Green Lane, PA, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Passing this threshold during your blower door test in Green Lane, PA ensures both energy savings and full compliance with local regulations.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use an air barrier system such as Tyvek or Zip Sheathing and verify that each seam is properly sealed with tape.
Place insulation with the accurate R-value and check for proper installation and full coverage in the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Make sure to seal all separations between conditioned and unconditioned areas, including crawl spaces, basements, and attics.
Many local municipalities issue code compliance checklists — the Philadelphia example is available here.
Our team at Local Energy Audits employs thermal imaging, caulk, and spray foam to locate and repair leaks efficiently on-site./li>

Preparing for a Blower Door Test in Green Lane, PA

To get ready for blower door test in Green Lane, PA, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside 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 is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. 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. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Green Lane, PA efficiency standards.
