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. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Lansdowne, 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 complete blower door test in Lansdowne, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. 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 air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under PA conditions.

What Is A Passing Blower Door Test Score?

Homes throughout Lansdowne, PA are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Meeting this benchmark in your blower door test in Lansdowne, PA reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Lansdowne, PA

When preparing for blower door test in Lansdowne, PA, we first switch off the home’s heating, cooling, and exhaust systems. 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 sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. 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 Lansdowne, PA.
