What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Zionhill, 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 carry out blower door test in Zionhill, PA, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. 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 indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in PA.

What Is A Passing Blower Door Test Score?

In Zionhill, PA, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Passing this requirement during a blower door test in Zionhill, PA keeps your home efficient and aligned with local building code standards.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.

Preparing for a Blower Door Test in Zionhill, PA

We begin blower door test in Zionhill, 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. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. 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. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Zionhill, PA building codes.
