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. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Oradell, 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?

To execute blower door test in Oradell, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

In Oradell, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Passing this requirement during a blower door test in Oradell, NJ keeps your home efficient and aligned with local building code standards.

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.

Preparing for a Blower Door Test in Oradell, NJ

To ensure accuracy during blower door test in Oradell, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within 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. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Oradell, NJ building codes.
