What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Mechanicsville, PA finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Mechanicsville, PA, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the PA environment.

What Is A Passing Blower Door Test Score?

Properties in Mechanicsville, PA must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Achieving compliance in your blower door test in Mechanicsville, PA helps improve energy efficiency and meet all local code mandates.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Install an effective air barrier, for example Tyvek or Zip Sheathing, and make certain all seams are sealed with durable tape.
Use insulation with the right R-value and confirm it is properly installed throughout 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.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.
With caulk, spray foam, and advanced thermal imaging, Local Energy Audits locates and seals leaks efficiently on-site./li>

Preparing for a Blower Door Test in Mechanicsville, PA

Preparation for blower door test in Mechanicsville, PA begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. 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. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Mechanicsville, PA.

Blower Door Test for Contractors in Mechanicsville, PA
