What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Hi-Nella, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Hi-Nella, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Hi-Nella, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. 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 Hi-Nella, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Preparing for a Blower Door Test in Hi-Nella, NJ

We begin blower door test in Hi-Nella, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Hi-Nella, NJ.
