What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Estell Manor city, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Estell Manor city, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. 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 NJ.

What Is A Passing Blower Door Test Score?

In Estell Manor city, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Meeting this benchmark in your blower door test in Estell Manor city, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Why Do I Need A Blower Door Test?

The State of NJ, along with its municipalities, observes the IECC requirements, mandating blower door test for newly constructed or updated homes.

Homeowners benefit from blower door test in Estell Manor city, NJ because depressurization exposes airflow through cracks, helping identify leaks and boost efficiency.

Preparing for a Blower Door Test in Estell Manor city, NJ

Before conducting blower door test in Estell Manor city, NJ, we make sure all heating, cooling, and ventilation fans are switched off. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. 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 technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Estell Manor city, NJ efficiency codes.
