Blower Door Test in New Providence, NJ

Test your home’s air barriers and meet energy regulations through dependable blower door test in New Providence, NJ. Our professional technicians help homeowners, builders, and contractors identify air leaks, improve home comfort, and satisfy NJ energy code regulations.

What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in New Providence, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in New Providence, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. 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 expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

In New Providence, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. When your blower door test in New Providence, NJmeets this requirement, you benefit from reduced energy bills and code compliance.

Why Do I Need A Blower Door Test?

Both NJ and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures. We work closely with home builders, contractors, and homeowners who need blower door test in New Providence, NJ to ensure compliance and successful project completion. You may also need a duct leakage test if your ductwork or HVAC equipment lies outside the home’s thermal envelope. Learn more about energy code compliance.

A blower door test in New Providence, NJ helps homeowners discover inefficiencies. Depressurizing the home makes leaks more noticeable and highlights where energy can be conserved. It only takes a few hours to perform a blower door test, but the long-lasting impact on comfort and efficiency is felt through NJ’ hot summers and cool winters.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use a reliable air barrier like Tyvek or Zip Sheathing and make sure all seams are securely taped.
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.
Seal the transitions between conditioned and unconditioned zones, particularly around basements, attics, and crawl spaces.
Many cities provide compliance checklists through their building departments — see the Philadelphia version here.
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 New Providence, NJ

Before starting blower door test in New Providence, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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 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 depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in New Providence, NJ.

Blower Door Test for Contractors in New Providence, NJ

When contractors perform blower door test in New Providence, NJ, minor issues in professionally insulated homes can usually be resolved during the inspection. Using easy-to-apply materials like chalk and spray foam, we can correct small leaks or gaps during the test itself.
