Blower Door Test in Matawan, NJ

Assess your home’s air sealing and energy standards with trusted blower door test in Matawan, NJ. Our certified experts assist homeowners, builders, and contractors in improving comfort, sealing leaks, and meeting NJ energy code requirements.

What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Matawan, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Matawan, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

Houses in Matawan, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Achieving this goal during your blower door test in Matawan, NJ promotes energy savings and demonstrates adherence to local building rules.

Why Do I Need A Blower Door Test?

Both NJ and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures. Our experts assist home builders, contractors, and homeowners needing blower door test in Matawan, NJ to ensure compliance with energy codes and complete final permits. A duct leakage test is sometimes required if any HVAC components or duct lines are found beyond the building’s thermal envelope. Learn more about energy code compliance.

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

Preparing for a Blower Door Test in Matawan, NJ

Preparation for blower door test in Matawan, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other 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 depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Matawan, NJ.
