Ensure your home is sealed properly and energy-efficient with quality blower door test in Ocean City, NJ. Our skilled technicians help homeowners, builders, and contractors find air leaks, increase comfort, and comply with NJ energy standards.

What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. 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. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Ocean City, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Ocean City, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. 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 Ocean City, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Satisfying this requirement in your blower door test in Ocean City, NJ helps optimize energy use and ensures you meet local building standards.

Employ an appropriate air barrier system such as Tyvek or Zip Sheathing and verify that each seam has been correctly 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.
Ensure complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Ocean City, NJ

Getting ready for blower door test in Ocean City, NJ involves turning off all heating, cooling, and exhaust ventilation systems. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. 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. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Ocean City, NJ efficiency codes.

Blower Door Test for Contractors in Ocean City, NJ

For contractors arranging blower door test in Ocean City, NJ, most homes with professional insulation can handle small air leakage issues during the test itself. With materials such as chalk and spray foam, most small leaks or gaps can be sealed immediately on-site.
