What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Conshohocken, PA detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Conshohocken, PA, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in PA.

What Is A Passing Blower Door Test Score?

Properties in Conshohocken, PA must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Complying with this benchmark during a blower door test in Conshohocken, PA helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Conshohocken, PA

As part of preparing for blower door test in Conshohocken, PA, we power down the HVAC system along with kitchen and bathroom exhaust fans. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part 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. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to 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. 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 Conshohocken, PA.
