What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Media, PA detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Media, 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. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the PA climate.

What Is A Passing Blower Door Test Score?

In Media, PA, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Passing this requirement during a blower door test in Media, PA keeps your home efficient and aligned with local building code standards.

Why Do I Need A Blower Door Test?

Homeowners experience real energy benefits from blower door test in Media, PA. The fan’s depressurization highlights air leaks, helping identify inefficiencies that can be sealed for savings. A blower door test takes only a short time to complete but can have a lasting effect on your home’s comfort and energy efficiency through PA’ hot and cool seasons.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use Tyvek or Zip Sheathing as your air barrier and carefully tape all seams to prevent air leakage.
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.
Seal the transitions between conditioned and unconditioned zones, particularly around basements, attics, and crawl spaces.
Many building departments provide step-by-step compliance guides — you can find the Philadelphia example here.
With the help of thermal imaging tools, caulk, and spray foam, Local Energy Audits efficiently detects and seals leaks on-site./li>

Preparing for a Blower Door Test in Media, PA

We start the process of blower door test in Media, PA by ensuring all heating, air conditioning, and exhaust systems are turned off. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Media, PA.
