Re: Dont have your machine room at the top of a building
We had central air in one of the houses I lived in, with a duct right over my bed. One night in the early summer, when we first turned on the A/C, I was reading a book in bed and noticed a tiny spider on the page. I looked over and the bed was coated with them; there was a nest in the duct that got blown out into my room. I'll take cement dust any day.
