Ensure your property meets energy codes and maintains efficiency through expert blower door test in Modena, PA. Our experts help homeowners, builders, and contractors pinpoint air leaks, improve efficiency, and comply with PA building energy standards.

What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall 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 Modena, PA helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Modena, PA, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. 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 Modena, PA, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Satisfying this requirement in your blower door test in Modena, PA helps optimize energy use and ensures you meet local building standards.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an appropriate air barrier, such as Tyvek or Zip Sheathing, making sure every seam is correctly taped for maximum performance.
Ensure the insulation used meets the proper R-value and is well fitted throughout the structure’s building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal every transition point between conditioned and unconditioned environments, including attics, crawl spaces, and basements.
Many cities provide compliance checklists through their building departments — see the Philadelphia version here.
Local Energy Audits technicians carry thermal imaging devices, caulk, and spray foam to pinpoint and seal air leaks immediately./li>
Typically, over 90% of the time we record a passing score in two hours and handle all permit-related documentation.

Preparing for a Blower Door Test in Modena, PA

As part of preparing for blower door test in Modena, PA, we power down the HVAC system along with kitchen and bathroom exhaust fans. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. 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. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Modena, PA.
