Dehumidifier or Supplied Air

There is a debate about the benefits of a dehumidifier in a sealed crawlspace. The traditional way of providing humidity control in a sealed crawlspace is with supplied air from your HVAC system. In fact, that is the current building code. However, there is growing evidence that a correctly sized dehumidifier is better at regulating the humidity in the crawlspace. For example, if you go out of town for a weeks vacation, the chances are you have set your thermostat at a higher temperature than normal. That means the HVAC is not running which causes the humidity in the crawlspace to become elevated. A better choice would be to install a proper dehumidifier with a humidity gauge to regulate the humidity. With a dehumidifier in the crawlspace, you do not have to worry about running the HVAC to regulate the crawlspace.
