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. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Newfield, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Newfield, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

What Is A Passing Blower Door Test Score?

Houses in Newfield, 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. When your blower door test in Newfield, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Why Do I Need A Blower Door Test?

The State of NJ and local municipalities have implemented the IECC code, which mandates blower door test on new and remodeled residential homes. We often work with home builders, contractors, and homeowners requiring blower door test in Newfield, NJ to meet local energy codes and obtain permit approval.

Preparing for a Blower Door Test in Newfield, NJ

We start the process of blower door test in Newfield, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. 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. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Newfield, NJ.
