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. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in New Berlinville, PA locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in New Berlinville, PA, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

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. 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?

Properties in New Berlinville, PA must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Complying with this benchmark during a blower door test in New Berlinville, PA helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in New Berlinville, PA

To prepare a home for blower door test in New Berlinville, PA, we shut off the HVAC system and disable all exhaust fans. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in New Berlinville, PA.
