Blower Door Test in Egg Harbor, NJ

Evaluate your home’s air leakage and achieve energy compliance with precise blower door test in Egg Harbor, NJ. Our qualified technicians assist homeowners, builders, and contractors in detecting air leaks, optimizing comfort, and maintaining compliance with NJ energy codes.

What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Egg Harbor, 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?

When performing blower door test in Egg Harbor, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. 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?

Homes built in Egg Harbor, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. By meeting this standard in your blower door test in Egg Harbor, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Homeowners experience real energy benefits from blower door test in Egg Harbor, NJ. The fan’s depressurization highlights air leaks, helping identify inefficiencies that can be sealed for savings. Although it’s a short process, a blower door test produces a long-lasting impact by improving comfort and lowering energy costs throughout NJ’ climate extremes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use materials like Tyvek or Zip Sheathing as your air barrier and ensure every seam is well taped for best results.
Use properly rated insulation with the right R-value and ensure consistent coverage throughout 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 any gaps connecting conditioned and unconditioned spaces, such as those leading to basements, attics, or crawl spaces.
Many local municipalities issue code compliance checklists — the Philadelphia example is available here.
Using thermal imaging technology along with caulk and spray foam, Local Energy Audits identifies and seals leaks during the inspection./li>
In more than 90% of cases, we secure a passing score within two hours and deliver the paperwork needed to close the permit.

Preparing for a Blower Door Test in Egg Harbor, NJ

When preparing for blower door test in Egg Harbor, NJ, we first switch off the home’s heating, cooling, and exhaust systems. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to 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 sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Egg Harbor, NJ building codes.

Blower Door Test for Contractors in Egg Harbor, NJ

When contractors perform blower door test in Egg Harbor, NJ, minor issues in professionally insulated homes can usually be resolved during the inspection. Using simple yet effective materials like chalk and spray foam, we can seal most small leaks or gaps right during testing.
