Blower Door Test in Lodi, NJ

Achieve peak energy efficiency and verify airtight construction with professional blower door test in Lodi, NJ. Our certified technicians assist homeowners, builders, and contractors in detecting hidden air leaks, boosting comfort, and ensuring full compliance with NJ energy codes.

What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Lodi, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Lodi, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Construction in Lodi, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Achieving this standard in your blower door test in Lodi, NJ lowers utility bills and guarantees adherence to local code requirements.

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 professionals frequently support home builders, contractors, and homeowners who need blower door test in Lodi, NJ to comply with energy codes and finalize projects. If ducts or HVAC units are located outside the thermal envelope, a duct leakage test may also be mandated. Learn more about energy code compliance.

Homeowners experience real energy benefits from blower door test in Lodi, NJ. The fan’s depressurization highlights air leaks, helping identify inefficiencies that can be sealed for savings. 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 Tyvek or Zip Sheathing as your air barrier and carefully tape all seams to prevent air leakage.
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 all penetrations between conditioned and unconditioned areas—like attics, basements, and crawl spaces—are tightly sealed.
Building departments typically release step-by-step compliance lists — download the Philadelphia sample here as an example.
With caulk, spray foam, and advanced thermal imaging, Local Energy Audits locates and seals leaks efficiently on-site./li>
We achieve a passing score within two hours in over 90% of cases and promptly issue the documents to finalize your permit.

Preparing for a Blower Door Test in Lodi, NJ

To prepare a home for blower door test in Lodi, NJ, we shut off the HVAC system and disable all exhaust fans. 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 preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Lodi, NJ.

Blower Door Test for Contractors in Lodi, NJ

Contractors arranging blower door test in Lodi, NJ will find that homes with professional insulation can typically resolve small issues right on-site during testing. With materials such as chalk and spray foam on hand, minor leaks or gaps can usually be sealed immediately. In over 90% of cases, we are able to reach a passing blower door test score in under two hours and supply all necessary paperwork to finalize the building permit right away.
