What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Forest Grove, 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 complete blower door test in Forest Grove, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. 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 Forest Grove, PA, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Passing this threshold during your blower door test in Forest Grove, PA ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Forest Grove, PA

To prepare a home for blower door test in Forest Grove, PA, we shut off the HVAC system and disable all exhaust fans. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Forest Grove, PA energy efficiency codes.
