What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Newtown, 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?

To complete blower door test in Newtown, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. 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?

In Newtown, PA, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Passing this requirement during a blower door test in Newtown, PA keeps your home efficient and aligned with local building code standards.

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 regularly provide blower door test in Newtown, PA for home builders, contractors, and homeowners working to meet local code requirements and close permits. If any part of the HVAC system or ductwork sits beyond the building’s thermal envelope, a duct leakage test may be required. Learn more about energy code compliance.

Homeowners experience real energy benefits from blower door test in Newtown, PA. The fan’s depressurization highlights air leaks, helping identify inefficiencies that can be sealed for savings. It only takes a few hours to perform a blower door test, but the long-lasting impact on comfort and efficiency is felt through PA’ hot summers and cool winters.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an air barrier like Tyvek or Zip Sheathing, making sure all connecting seams are properly taped and sealed.
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.
Close any gaps connecting conditioned and unconditioned spaces, such as those leading to basements, attics, or crawl spaces.
Building departments typically release step-by-step compliance lists — download the Philadelphia sample here as an example.
Local Energy Audits identifies and repairs leaks on-site using thermal imaging tools, caulk, and high-quality spray foam./li>
Over 90% of the time, we complete testing with a passing score in two hours or less and handle all permit paperwork on-site.

Preparing for a Blower Door Test in Newtown, PA

To ensure accuracy during blower door test in Newtown, PA, we begin by switching off the HVAC system and all exhaust fans in 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. 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. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Newtown, PA.

Blower Door Test for Contractors in Newtown, PA

During blower door test in Newtown, PA, contractors will find that well-insulated homes can manage minor issues directly on-site. With materials such as chalk and spray foam, most small leaks or gaps can be sealed immediately on-site. In more than 90% of cases, we achieve a passing blower door test score within two hours and provide complete documentation to close out the building permit the same day.
