broken ac duct work.
At my rental house (split level home) the renters broke loose the duct work under the house in the crawl space. Did not let me know for a week at least and yet let the A/C run constantly for a week. (This was in hot part of June/July) The duct work in the house in basement area started to condensate and wet the sheetrock. Could this broken duct work have caused this problem since it ran the A/C for a week straight? They kept thermastat below 70 and said they kept lowering it to see if it would cool.
