What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Riverside, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Riverside, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. 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 air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

Properties in Riverside, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Complying with this benchmark during a blower door test in Riverside, NJ helps cut energy expenses and meet local building regulations.

Why Do I Need A Blower Door Test?

In accordance with the IECC, the State of NJ and various local authorities require blower door test for new or remodeled residential properties. Our certified technicians assist home builders, contractors, and homeowners with blower door test in Riverside, NJ to meet energy requirements and wrap up permit approvals.

Homeowners can greatly benefit from blower door test in Riverside, NJ. The depressurization process makes air leaks noticeable, helping pinpoint trouble areas and improve energy efficiency. A short blower door test can result in a long-lasting impact on your home’s energy efficiency, comfort, and year-round performance in NJ.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use an air barrier system such as Tyvek or Zip Sheathing and verify that each seam is properly sealed with tape.
Install correctly rated insulation with the proper R-value and confirm it’s well positioned in every part of 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.
Ensure complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.
Local code departments usually provide a checklist to assist with compliance — see the Philadelphia example here.
Local Energy Audits identifies and repairs leaks on-site using thermal imaging tools, caulk, and high-quality spray foam./li>
More than 90% of the time, we deliver a passing score in under two hours and issue all documents needed for permit approval.

Preparing for a Blower Door Test in Riverside, NJ

To get ready for blower door test in Riverside, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. 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. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Riverside, NJ.
