Condensation on Lower-Level Ceiling

bailloup | Posted in General Questions on

Hi, I live in a 2 story home in Florida where the temperature is in the mid eighties to mid nineties most days , daytime my central air conditioning is set between 70-75 degrees. At night the ac is lowered to 68 degrees. For the last few week each morning I noticed that there is condensation on my family room ceiling.  This area is located 4 feet away from the back a Patio door and about 7 ft from the nearest ac vent  the kitchen is next to the family room , located above this area is a bedroom that I checked and found no wet surface.
can anyone help as to what might be causing the problem or who do I called to check the problem. Any help is appreciated. Thank you. I’ve live here for 23 years and has never had this problem.

    Is your indoor humidity staying below 60%? There is no possibility of a water leak above?

    Air infiltration is another possibility.

      Hi, the thermometer humidity gauge this morning read 58% humidity and the indoor temperature was 68 degrees, same as the ac. I will continue to watch the humidity reading . I just got the device yesterday. Thank you.

    Is the central air unit located in the attic? Is so, is it near the wet area? Do you know how the ductwork is run?

    No the central air unit is located on the upper level in a closet next to the master bedroom. I do not know how the ductwork is run. I purchased the home from a developer, it was already built. Who would you suggest I contact for this type of problem? Thank you.
