Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Earlville, PA, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. 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?

In Earlville, PA, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Meeting this requirement during your blower door test in Earlville, PA helps reduce energy costs while keeping your home compliant with local building codes.

Homeowners gain major advantages from blower door test in Earlville, PA. As the fan depressurizes the home, incoming air through leaks becomes easier to detect, revealing problem spots and potential energy-saving improvements.

Preparing for a Blower Door Test in Earlville, PA

Getting ready for blower door test in Earlville, PA involves turning off all heating, cooling, and exhaust ventilation 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. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. 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 air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Earlville, PA efficiency codes.
