Those of you with weekend homes on the coast that stay vacant for a week or two between uses. Do you leave your AC running, use some type of dehumidifier, or do nothing but close it up when you leave. I have a place in POC and have been having severe allergies when I am there on the weekends. By Sunday morning I am clawing my eyes out, stopped up, and sneezing like crazy. It seems to affect me more at night while in bed. I have metal building finshed on the in side with sheet rock walls with central air.
