Non-louvered in furnace room

[Chris Lower]

I would like to install non-louvered doors on my utility closet containing the furnace, hot water heater and washer dryer. The closet in my 1972 home sits above the crawlspace and I need to find out how to ventilate it in replacement of the current louvered doors. I calculated the needed venting to be 150 cubic inch of air. Will venting the floor of the utility closet into the crawl space give me a lot of humidity in the closet? I have plastic covering the ground in crawlspace but have a few spots with water on top of it. The closet is at the back of my dining room and I would prefer to hide the vents within the closet.

You can install a floor register accessing your crawlspace for makeup air and not even use a door louver. Also install some kind of screened louver on your outside wall to the crawlspace so air can get in there. you might even reduce the amount of humidity if you have circulating air within the crawlspace.
