Hi... We recently bought our house and discovered that the heating system is a forced air system, but does not have any ducts from the furnace to the floor vents. The heat apparently fills the crawl space and then the warm air gets pushed up the vent holes, as well as up "ducts" made out of the dry wall and studs in the walls.
Is this safe? is this normal? we are concerned about breathing the dirt, dust, bugs and PINK INSULATION that is sitting just inside the floor vents. it is apparent that the crawl space does not have a vent out system, as the air blows up the vents pretty good, with no other place to go.
We have thin mini filters under the vents, but that can't be enough...? the bottom of the crawl space is just medium sized rocks, I dont believe there is a vapor barrier under it either...
Our inspector seemed to have completely missed this fact about our heating system and didn't alert us to how it was made. We are considering taking him to court, because we wouldn't have bought the house like this, or would have asked the seller to fix it.
I guess I am asking is this system normal? should our inspector have noticed this?? can we fix it? and to what extent are we looking at on this project? I am thinking we just need to hook up a ducting system to all the vents.
the furnace is electric, and its just sitting in a closet, it's not even attached or screwed down and blows into the crawl space through a hole in the bottom of the closet.
any input or suggestions are most welcomed!
