What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Mantua, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Mantua, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. 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 the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

In Mantua, 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. By meeting this standard in your blower door test in Mantua, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Homeowners experience real energy benefits from blower door test in Mantua, NJ. The fan’s depressurization highlights air leaks, helping identify inefficiencies that can be sealed for savings.

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.
  • Ensure insulation with the specified R-value is properly installed and fitted throughout the entire 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.
  • Many building departments provide step-by-step compliance guides — you can find the Philadelphia example here.
  • Local Energy Audits brings thermal cameras, caulk, and spray foam to locate and seal leaks while performing on-site testing./li>
  • In the majority of cases—over 90%—we reach a passing score within two hours and provide all closing documentation.

Preparing for a Blower Door Test in Mantua, NJ

We start the process of blower door test in Mantua, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Mantua, NJ.

Blower Door Test for Contractors in Mantua, NJ

For contractors overseeing blower door test in Mantua, NJ, most properly insulated homes can manage small on-site repairs during testing. With materials such as chalk and spray foam, most small leaks or gaps can be sealed immediately on-site.
