What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Paulsboro, NJ 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?

For accurate blower door test in Paulsboro, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

In Paulsboro, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. When your blower door test in Paulsboro, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Preparing for a Blower Door Test in Paulsboro, NJ

When preparing for blower door test in Paulsboro, NJ, we first switch off the home’s heating, cooling, and exhaust systems. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces 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. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Paulsboro, NJ energy efficiency codes.
