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. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Avalon, 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?

When performing blower door test in Avalon, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

What Is A Passing Blower Door Test Score?

In Avalon, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. When your blower door test in Avalon, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Why Do I Need A Blower Door Test?

The State of NJ and its local governments follow the IECC standards, which require blower door test on newly built or remodeled residential dwellings. Our company assists home builders, contractors, and homeowners who rely on blower door test in Avalon, NJ to fulfill energy code compliance and finalize construction permits. A duct leakage test could be required when air ducts or HVAC units extend outside the structure’s thermal envelope. Learn more about energy code compliance.

Homeowners experience real energy benefits from blower door test in Avalon, NJ. The fan’s depressurization highlights air leaks, helping identify inefficiencies that can be sealed for savings. Taking only a few hours, a blower door test creates a long-lasting impact by improving comfort, performance, and efficiency in NJhomes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an air barrier like Tyvek or Zip Sheathing, making sure all connecting seams are properly taped and sealed.
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.
Seal the transitions between conditioned and unconditioned zones, particularly around basements, attics, and crawl spaces.
Many local building offices offer a step-by-step checklist to confirm compliance — view the Philadelphia sample here.
Local Energy Audits identifies and repairs leaks on-site using thermal imaging tools, caulk, and high-quality spray foam./li>
Over 90% of our projects pass within two hours, with all required paperwork issued immediately to close the permit.

Preparing for a Blower Door Test in Avalon, NJ

As part of preparing for blower door test in Avalon, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Avalon, NJ.
