What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Ridgewood, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Ridgewood, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

In Ridgewood, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Satisfying this requirement in your blower door test in Ridgewood, NJ helps optimize energy use and ensures you meet local building standards.

Homeowners gain major advantages from blower door test in Ridgewood, NJ. As the fan depressurizes the home, incoming air through leaks becomes easier to detect, revealing problem spots and potential energy-saving improvements. Although it’s a short process, a blower door test produces a long-lasting impact by improving comfort and lowering energy costs throughout NJ’ climate extremes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Install an effective air barrier, for example Tyvek or Zip Sheathing, and make certain all seams are sealed with durable tape.
Use insulation with the right R-value and confirm it is properly installed throughout 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.
Make sure to seal all separations between conditioned and unconditioned areas, including crawl spaces, basements, and attics.
Building departments typically release step-by-step compliance lists — download the Philadelphia sample here as an example.

Preparing for a Blower Door Test in Ridgewood, NJ

To prepare for blower door test in Ridgewood, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Ridgewood, NJ.
