What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Red Hill, PA identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Red Hill, PA, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. 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?

In Red Hill, PA, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Achieving compliance in your blower door test in Red Hill, PA helps improve energy efficiency and meet all local code mandates.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Red Hill, PA

To properly prepare for blower door test in Red Hill, 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. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and 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. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Red Hill, PA.
