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. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Clayton borough, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Clayton borough, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

Properties in Clayton borough, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Reaching the target during your blower door test in Clayton borough, NJ guarantees lower energy consumption and full code compliance.

Install a quality air barrier like Tyvek or Zip Sheathing and confirm that all joints and seams are completely taped.
Install insulation with the appropriate R-value and ensure it is correctly fitted across 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.
Seal every transition point between conditioned and unconditioned environments, including attics, crawl spaces, and basements.
Local code departments usually provide a checklist to assist with compliance — see 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>

Preparing for a Blower Door Test in Clayton borough, NJ

We start the process of blower door test in Clayton borough, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. 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. 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 occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Clayton borough, NJ.
