What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Ferndale, PA helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Ferndale, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in PA.

What Is A Passing Blower Door Test Score?

In Ferndale, PA, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Passing this requirement during a blower door test in Ferndale, PA keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Ferndale, PA

We begin blower door test in Ferndale, PA by switching off the HVAC system and shutting down all exhaust fans throughout the home. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces 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. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to 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 sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Ferndale, PA.
