What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Ramsey, 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?

When performing blower door test in Ramsey, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

In Ramsey, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Meeting this benchmark in your blower door test in Ramsey, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Why Do I Need A Blower Door Test?

The State of NJ, together with many cities and counties, enforces the IECC (International Energy Conservation Code), which calls for blower door test on new or renovated residential properties. We proudly serve home builders, contractors, and homeowners who need blower door test in Ramsey, NJ to pass inspections and fulfill energy code obligations. A duct leakage test is often required whenever ducts or HVAC units are found outside the building’s thermal envelope. Learn more about energy code compliance.

Homeowners benefit from blower door test in Ramsey, NJ because depressurization exposes airflow through cracks, helping identify leaks and boost efficiency. A blower door test usually takes just a few hours but delivers a long-lasting impact on your home’s comfort, performance, and efficiency—particularly during NJ’ hot summers and cool winters.

How To Pass A Blower Door Test:

Use materials like Tyvek or Zip Sheathing as your air barrier and ensure every seam is well taped for best results.
Install correctly rated insulation with the proper R-value and confirm it’s well positioned in every part of the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Properly seal all connections between conditioned and unconditioned zones, including basements, crawl spaces, and attics.
Most building departments provide detailed compliance resources — view the Philadelphia checklist example here.

Preparing for a Blower Door Test in Ramsey, NJ

Before starting blower door test in Ramsey, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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 everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Ramsey, NJ.
