Blower Door Test in Trenton, NJ

Find and fix air leaks while improving performance through reliable blower door test in Trenton, NJ. Our certified technicians provide homeowners, builders, and contractors with expert air leak detection, better comfort, and complete NJ energy code compliance.

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. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Trenton, 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?

While performing blower door test in Trenton, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Properties in Trenton, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Achieving this standard in your blower door test in Trenton, NJ lowers utility bills and guarantees adherence to local code requirements.

Why Do I Need A Blower Door Test?

NJ and local city codes follow the IECC (International Energy Conservation Code), which mandates blower door tests on residential buildings after construction or renovation. We work closely with home builders, contractors, and homeowners who need blower door test in Trenton, NJ to ensure compliance and successful project completion. A duct leakage test may also be performed when ductwork or HVAC equipment extends beyond the thermal envelope. Learn more about energy code compliance.

Homeowners experience real energy benefits from blower door test in Trenton, NJ. The fan’s depressurization highlights air leaks, helping identify inefficiencies that can be sealed for savings. Completing a blower door test takes just a few hours, yet its long-lasting impact enhances comfort and performance in every NJseason.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an appropriate air barrier, such as Tyvek or Zip Sheathing, making sure every seam is correctly taped for maximum performance.
Place insulation with the accurate R-value and check for proper installation and full coverage in 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.
Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.
Local building departments often supply a detailed checklist to ensure compliance — you can download the Philadelphia example here for guidance.
Local Energy Audits is equipped with thermal imaging tools, caulk, and spray foam to find and seal air leaks immediately on-site./li>
Typically, over 90% of the time we record a passing score in two hours and handle all permit-related documentation.

Preparing for a Blower Door Test in Trenton, NJ

We begin blower door test in Trenton, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. 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 occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Trenton, NJ efficiency codes.
