What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Holmes, PA finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Holmes, PA is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

What Is A Passing Blower Door Test Score?

In Holmes, PA, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. When your blower door test in Holmes, PA meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Preparing for a Blower Door Test in Holmes, PA

Preparation for blower door test in Holmes, PA begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond 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 structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Holmes, PA efficiency standards.
