What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Bayonne, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Bayonne, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

Houses in Bayonne, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Achieving this standard in your blower door test in Bayonne, NJ lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Bayonne, NJ

When preparing for blower door test in Bayonne, NJ, we first switch off the home’s heating, cooling, and exhaust systems. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond 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. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and 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. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Bayonne, NJ efficiency codes.
