What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Wayne, PA makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Wayne, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

In Wayne, PA, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Reaching this target in your blower door test in Wayne, PA helps maintain lower energy bills and fulfills local code obligations.

Why Do I Need A Blower Door Test?

PA and local city codes follow the IECC (International Energy Conservation Code), which mandates blower door tests on residential buildings after construction or renovation. We provide support to home builders, contractors, and homeowners needing blower door test in Wayne, PA for meeting energy efficiency standards and finalizing permits. If ducts or HVAC units are located outside the thermal envelope, a duct leakage test may also be mandated. Learn more about energy code compliance.

Homeowners gain major advantages from blower door test in Wayne, PA. As the fan depressurizes the home, incoming air through leaks becomes easier to detect, revealing problem spots and potential energy-saving improvements. Though a blower door test lasts just a few hours, it offers a long-lasting impact on your home’s comfort, durability, and performance year-round in PA.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Install a quality air barrier like Tyvek or Zip Sheathing and confirm that all joints and seams are completely taped.
Fit insulation with the correct R-value and make sure it’s installed without voids across the entire 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 gaps and openings separating conditioned spaces from unconditioned areas, including crawl spaces, basements, and attics.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.
Equipped with thermal imaging tools, caulk, and spray foam, Local Energy Audits can find and fix leaks directly at your property./li>

Preparing for a Blower Door Test in Wayne, PA

We begin blower door test in Wayne, PA by switching off the HVAC system and shutting down all exhaust fans throughout the home. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing 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. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Wayne, PA.

Blower Door Test for Contractors in Wayne, PA

For contractors conducting blower door test in Wayne, PA, well-insulated homes generally require only minimal on-site corrections during the test.
