One previous poster recommended running fan at all times. My control board was damaged by a surge and caused my units fan to run continuously during the summer. After some time , I started noticing mildew forming on some old leather shoes in the bedroom closet. Also noticed that outlet ducks in the master bedroom tended to get moist and some growth was forming. Checked the humidity in that room and was in the high 60s. Later had AC company check the unit and they replaced the damaged control board. Was told that in the humid months in the south , that you do not want to run the fan at all times. While the AC is running , you are reducing humidity in the air by having it condense vapor on the coil. When the AC shuts off, you want the fan to also shut off. If not you are blowing the air over the wet condenser and sending it back into the house. Since then , I have made sure the fan is not running after AC shutdown and the humidity is much lower.
To be safe from mold, was convinced to buy UV light (Guardian Air Reme) and charged about $1000. Was reminded of tis when my AC company recently called and said it was time for the Reme Cell to be replaced. $400. Was never told about that. Decided to investigate. Found out Reme cost was about $429 and cell(Light Bulb) is about $200 and is supposed to be easily changed. So, be prepared to have somebodies hand in your back pocket.
