What could be happening?
Hello. Not sure if this is a disaster or not but I suppose it has potential so I am posting here....
We moved into a log house about 3 yrs ago. It has 2 levels and basement. There are 2 a/c units...the unit on the upper level was broken but we recently fixed it. Soon after (and this may be coincidental) the a/c was fixed white particles started falling from the ceiling...at least that's where they appear to be coming from. My husband thinks we have carpenter ants or termites. I maintain that termites come into a house on the ground level if any wood is exposed and in contact w/soil outside otherwise they won't chew through concrete (base of house is concrete) and if we had carpenter ants in the roof we would be seeing the occasional ant on the ceiling by now and we would smell the nest....in my experience carpenter ant nests are smelly! I think the white stuff may have something to do w/the fixed a/c? I haven't ruled out critters though....has anyone had a similar problem? And if so, how did you figure out what was causing the problem and how did you fix it?
Thanks for any input!
