What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Kimberton, PA identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Kimberton, PA, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare 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 from inside, exterior air flows in through leaks and gaps in the building envelope. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

Houses in Kimberton, PA are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version.

Preparing for a Blower Door Test in Kimberton, PA

To prepare a home for blower door test in Kimberton, PA, we shut off the HVAC system and disable all exhaust fans. 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. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Kimberton, PA energy standards.
