Vent Intelligence

Crawl space ventilation is a complex problem in this area of NC.  Significant periods outside air is more humid than crawlspace air.  However, low dew points in the crawlspace can cause significant condensation water whether vents are open or closed.  And this can produce mold, rot, and termites.

If you think you have moisture problems in the crawlspace I suggest you understand the facts before making any investment.  This is especially true when replacing your HVAC system or ducting.

I plan to write an article on this topic in the near future or you can call me.
