I noticed that in my new home the home builder put 2 vents in the cold
storage room. That's wonderful but both vents are the flap kind ??
How is air suppose to get and out if the vents are closed 100% of the
time. Are the vents not suppose to be the kind that are constructed
open wtih a screen inside to prevent bugs from getting in ? There is
a really bad musty smell as well in the basement.
