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. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Palm, 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 conduct blower door test in Palm, PA, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. 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 indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the PA climate.

What Is A Passing Blower Door Test Score?

Homes in Palm, PA are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. 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 threshold during your blower door test in Palm, PA ensures both energy savings and full compliance with local regulations.

Why Do I Need A Blower Door Test?

The State of PA and its local governments follow the IECC standards, which require blower door test on newly built or remodeled residential dwellings. Our experts assist home builders, contractors, and homeowners needing blower door test in Palm, PA to ensure compliance with energy codes and complete final permits.

There are many benefits of blower door test in Palm, PA for homeowners. When the fan lowers indoor pressure, leaks become visible, allowing for easy identification of inefficiencies and energy-saving opportunities. A blower door test, typically lasting only a few hours, offers a long-lasting impact on your home’s performance, efficiency, and comfort across PA’ seasons.

Anticipate potential air leaks before testing begins.
Apply an appropriate air barrier, such as Tyvek or Zip Sheathing, making sure every seam is correctly taped for maximum performance.
Ensure insulation with the specified R-value is properly installed and fitted throughout 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.
Ensure complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Palm, PA

To prepare for blower door test in Palm, PA, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond 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. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Palm, PA energy code requirements.
