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. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Zionsville, PA helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Zionsville, PA, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

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 Zionsville, PA, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. By meeting this standard in your blower door test in Zionsville, PA, you can enjoy lower utility bills and peace of mind with code compliance.

Why Do I Need A Blower Door Test?

Choose Tyvek or Zip Sheathing as your air barrier and check that all seams are securely taped to maintain airtightness.
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 all joints and gaps that connect conditioned and unconditioned areas such as basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Zionsville, PA

We begin blower door test in Zionsville, PA by switching off the HVAC system and shutting down all exhaust fans throughout the home. 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. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. 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. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Zionsville, PA energy standards.

Blower Door Test for Contractors in Zionsville, PA

For contractors overseeing blower door test in Zionsville, PA, most properly insulated homes can manage small on-site repairs during testing.
