Improves indoor air quality by creating air exchanges in the home

  • An air intake or vent is installed on the first floor of the home allowing a small amount of indoor air to be exhausted out through the crawlspace.
  • On average, one air exchange of outdoor air is brought into the home each day.
  • Chemicals, mold spores, and contaminated air will not infiltrate a home from the crawl space while the system is running due to the negative pressure created in the crawl space.
  • Air exchanges are created in the crawl space by exchanging contaminated air with fresh air.

Is energy efficient and in line with green standards

  • The entire system runs on less than 3 amps.
  • The system keeps the crawl space about 10 to 15 degrees Fahrenheit cooler in the summer months.
  • A cooler crawl space means a cooler sub floor and floor. This will enable the HVAC system to run less, thereby reducing energy consumption of the home.

Is simple to install and maintenance free

  • The average system can be installed easily and requires less than $500 in electrical work to prepare the crawl space for the NAS Crawl System.
  • Run the system through the spring, summer, and fall. Turn it off through the winter. No system maintenance required.
  • Very affordable and significantly contributes to preserving home value and individual health.
