What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in West Point, PA helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in West Point, PA, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under PA weather.

What Is A Passing Blower Door Test Score?

Properties in West Point, PA must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Achieving this standard in your blower door test in West Point, PA lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in West Point, PA

To properly prepare for blower door test in West Point, PA, the HVAC system and all bathroom and kitchen fans are turned off. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. 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 West Point, PA.

Blower Door Test for Contractors in West Point, PA

When contractors perform blower door test in West Point, PA, minor issues in professionally insulated homes can usually be resolved during the inspection.
