I'm new in humid central Florida and have two thru-wall room AC units. A large Freidrich one that also has resistance heating (for the couple of cool nights in "winter" here) and a small bedroom sized GoldStar one. The Friedrich does great and as I assumed all units did, drips condensate outside.
The smaller one was only being used at night with the bedroom door closed and the bigger unit off (to save elec. $s). Last week was the beginning of the most humid summer weather so I had the small one on one night (80 deg at 11pm, and 65% humidity, pre the weather report) with the door closed. I was cool overnight, but I also sweating... I began to wonder if a unit can blow cold air, but not be removing the moisture and instead be blowing it back into the room too?
I checked outside the next morning and some other time during the hot afternoon - and there was No dripping at all, while the other units was, as it always does. Looking up at the unit (on the second floor in the shade) I can see what looks like a black rubber plug on the face of the lower right corner of what I assume is the drain pan. I'd expected to see a tube - but not a plug...
Can a unit run right with no drainage?? I've even sensed a mild mildew-like smell when starting it up sometimes of a little while.
Any help will be appreciated!
