What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use 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 Gilbertsville, PA helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Gilbertsville, PA, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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 starts pulling air out, external air enters through the smallest cracks and leakage points. 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?

Homes built in Gilbertsville, PA are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Complying with this benchmark during a blower door test in Gilbertsville, PA helps cut energy expenses and meet local building regulations.

There are many benefits of blower door test in Gilbertsville, PA for homeowners. When the fan lowers indoor pressure, leaks become visible, allowing for easy identification of inefficiencies and energy-saving opportunities. Although it’s a short process, a blower door test produces a long-lasting impact by improving comfort and lowering energy costs throughout PA’ climate extremes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Employ an appropriate air barrier system such as Tyvek or Zip Sheathing and verify that each seam has been correctly taped.
Use properly rated insulation with the right R-value and ensure consistent coverage throughout 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.
Eliminate air leaks by sealing all openings between conditioned areas and unconditioned spaces, including basements and attics.
Many local municipalities issue code compliance checklists — the Philadelphia example is available here.
Local Energy Audits provides on-site leak detection and sealing using advanced thermal imaging tools, caulk, and spray foam./li>
We achieve a passing score within two hours in over 90% of cases and promptly issue the documents to finalize your permit.

Preparing for a Blower Door Test in Gilbertsville, PA

For blower door test in Gilbertsville, PA, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. 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 everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Gilbertsville, PA.
