What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Broomall, PA assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Broomall, PA, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the PA climate.

What Is A Passing Blower Door Test Score?

In Broomall, PA, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. 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 Broomall, PA helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Broomall, PA

Getting ready for blower door test in Broomall, PA involves turning off all heating, cooling, and exhaust ventilation systems. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Broomall, PA building codes.
