What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Linwood, 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?

In preparation for blower door test in Linwood, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. 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?

In Linwood, 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. Achieving compliance in your blower door test in Linwood, NJ helps improve energy efficiency and meet all local code mandates.

Why Do I Need A Blower Door Test?

The State of NJ, along with its municipalities, observes the IECC requirements, mandating blower door test for newly constructed or updated homes. We regularly provide blower door test in Linwood, NJ for home builders, contractors, and homeowners working to meet local code requirements and close permits. If any part of the HVAC system or ductwork sits beyond the building’s thermal envelope, a duct leakage test may be required. Learn more about energy code compliance.

Through blower door test in Linwood, NJ, homeowners can easily find leaks. When the fan reduces internal pressure, air movement through problem areas becomes noticeable, offering chances to save energy. Typically completed within a few hours, a blower door test provides a long-lasting impact on comfort, energy efficiency, and overall home performance in NJ’ varied climate.

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.
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.
Seal all openings between conditioned and unconditioned areas, including basements, attics, and crawl spaces.
Local jurisdictions frequently publish compliance checklists — the Philadelphia version can be downloaded here.
Local Energy Audits uses thermal imaging tools, caulk, and spray foam to detect and seal leaks directly 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 Linwood, NJ

Getting ready for blower door test in Linwood, NJ involves turning off all heating, cooling, and exhaust ventilation systems. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Linwood, NJ.
