I bought my small one-story house in 1996. It is now about 26 years old. There is no basement, but there is a crawl space under the entire house that I store a lot of stuff in. The pipes for the house's plumbing and the electrical and cable wires are all visible in the crawl space.
Recently I started hearing loud clicks coming from under the floor in the living room. I assumed they were coming from the crawl space, but when I went in it I heard nothing. Now the clicks have turned into what sounds like a noisy motor..
My oil furnace is in my garage and there's no sound coming from it. I've gone back into the crawl space and checked it out from wall to wall and still heard nothing, but when I go back into the living room the sound is still there.
Any ideas as to what's going on?
