The KA3 are workhorses and have very little issues. The S19, days above 90 I can’t keep them going. I have 2 AC units running and multiple fans blowing outside air.
It’s to the point I can’t run them during the day… I live in MS.
I’m going to remove the AC and add another fan to bring in the air… I have all the units duct to blow air out of room and also an exhaust fan…. Thanks for the info.
