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. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Woodland Park, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Woodland Park, 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 used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. 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 the fan starts pulling air out, external air enters through the smallest cracks and leakage points. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. 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?

Homes in Woodland Park, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version 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. Reaching this target in your blower door test in Woodland Park, NJ helps maintain lower energy bills and fulfills local code obligations.

Why Do I Need A Blower Door Test?

Through blower door test in Woodland Park, NJ, homeowners can easily find leaks. When the fan reduces internal pressure, air movement through problem areas becomes noticeable, offering chances to save energy. 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.
Choose Tyvek or Zip Sheathing as your air barrier and check that all seams are securely taped to maintain airtightness.
Ensure the insulation used meets the proper R-value and is well fitted throughout the structure’s building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.
Many local building offices offer a step-by-step checklist to confirm compliance — view the Philadelphia sample here.
Local Energy Audits is equipped with thermal imaging tools, caulk, and spray foam to find and seal air leaks immediately on-site./li>

Preparing for a Blower Door Test in Woodland Park, NJ

As part of preparing for blower door test in Woodland Park, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond 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 depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Woodland Park, NJ.
