Learned a lot over the last couple of days reading this site, thanks to all! I did a bunch off searching but didnt find anything that applied to to my situation /set up and the question I have.
We are in Savannah Georgia and recently moved into a 3200 sf single story home on the water surrounded by even more water. The house has HVAC 3 zones; 1. master br and bath, 2. main living area with kitchen, and 3. two additional bed rooms and a over the garage bonus room. Slab contruction and all are at ground level. We have 3 new HVAC systems of the same size. The problem we have is that the humidity is running very high, reaching 70% at times and the humidity differential from inside to outside averages only about 10%. I believe we need to install a whole house dehumidifier.
+Can a whole house dehumidifier be installed on one of the 3 systems and have an effect of lowering the humidity throughout the house? If so, my wife’s major concern is with the MB and bath at one end of the house. Or would it be better to put it in the middle system?
+Or - Would it be better to install ductwork between the systems so that a single whole house dehumidifier could service all areas? If so, would ducting between 2 systems be sufficient or would we have to incorporate all 3.
I understand that humidity flows from one area to another and will eventually equalize but for a single unit on one system to work the humidity would have to equalize better that temperature does.
I am trying to avoid the increased cost of three separate dehumidifiers.
Thank you in advance for your time.
