Insulation coming through vents
I have an insulation problem, it is coming through every vent in the home. It has ruined my carpets, it would take hours and days to get it cleaned only for it be the same way hours after. Under beds is the worst and inches thick! We cleaned our furnace where the filter sits. That entire area had insulation sticking to everything. This issue may be due to a non profit energy efficient company coming here to install extra insulation in our attic. I have researched this for hours, that looks to be the culprit, with moisture also having a possible effect as well. My daughters room is always the coldest, I read on a website about mold growth in that type of room. Sure enough upon pulling out the bed there was a small crack in the corner with black mold growing, window sills had small spots as well. We may in fact have several major problems if this moisture is as bad as I'm reading it could be. Everything stated, we have in this home. Concrete steps outside have shifted and are uneven with cracks in the sidewalk. Around the bathtub we had to recaulk due to the original clear caulk looking very dirty with black underneath it. We instead used white. Window sills are usually wet in the summer, the patio door seems to be worst. Below freezing temperatures causes ice build up on the inside of that one. Turning on the central air after not using it in a while has a very weird smell, hard to compare it to anything else. Ideas? Tips? This house was put here in 1980, and very well kept up, still is. These carpets are what is definitely bothersome, and worrying about the air quality with small children!
