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. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Montclair, NJ allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Montclair, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. 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.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. 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 Montclair, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Satisfying this requirement in your blower door test in Montclair, NJ helps optimize energy use and ensures you meet local building standards.

Why Do I Need A Blower Door Test?

The State of NJ and its local governments follow the IECC standards, which require blower door test on newly built or remodeled residential dwellings. Our team regularly helps home builders, contractors, and homeowners seeking blower door test in Montclair, NJ to satisfy energy code standards and close final inspections. A duct leakage test may also be necessary if any ducts or HVAC systems are positioned outside the building’s thermal envelope. Learn more about energy code compliance.

There are many benefits of blower door test in Montclair, NJ for homeowners. When the fan lowers indoor pressure, leaks become visible, allowing for easy identification of inefficiencies and energy-saving opportunities. This simple test, completed in a few hours, creates a long-lasting impact on your home’s efficiency and comfort during NJ’ hot and cold months.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an effective air barrier such as Tyvek or Zip Sheathing, ensuring every seam is tightly sealed with proper tape.
Use insulation that has the designated R-value and confirm it’s properly applied throughout the building envelope for maximum efficiency.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal all openings between conditioned and unconditioned areas, including basements, attics, and crawl spaces.
Building departments typically release step-by-step compliance lists — download the Philadelphia sample here as an example.

Preparing for a Blower Door Test in Montclair, NJ

To ensure accuracy during blower door test in Montclair, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside 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 the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Montclair, NJ energy efficiency codes.

Blower Door Test for Contractors in Montclair, NJ

During blower door test in Montclair, NJ, contractors will find that well-insulated homes can manage minor issues directly on-site.
