# of Attic Vents

[Guest guest]

I read that number of attic vents should be paired, so for each vent

that sits low in attic, there should be a corresponding one in upper

part of roof. Does that sound right? If there are more vents under

soffits than on roof, is that cause a problem? It seems like that

would just mean that some of the soffit vents would just not take in

any air since no place for air to escape. That doesn't sound like too

much of a problem to me. Do air quality professionals deal with this

or is that up to another type of contractor? Thanks
