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. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Milltown, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Milltown, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Milltown, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Passing this threshold during your blower door test in Milltown, NJ ensures both energy savings and full compliance with local regulations.

Why Do I Need A Blower Door Test?

The State of NJ, along with its municipalities, observes the IECC requirements, mandating blower door test for newly constructed or updated homes. Our certified technicians assist home builders, contractors, and homeowners with blower door test in Milltown, NJ to meet energy requirements and wrap up permit approvals.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal off any access points or gaps between conditioned and unconditioned spaces like attics, crawl spaces, and basements.

Preparing for a Blower Door Test in Milltown, NJ

Getting ready for blower door test in Milltown, NJ involves turning off all heating, cooling, and exhaust ventilation systems. 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. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and 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. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Milltown, NJ.
