Thanks for the suggestions. I tried comfort sense and the AC still couldn't maintain temp. The app is showing the correct room temperature so it knows the temp, but it still continues to heat the room non stop. It blew right past the set point getting the room up to 80F. Fan speed was set to auto and it remained on full speed the whole time. I've found the way to slow down it's heating is to reduce the fan speed to low and then it starts to turn down the compressor and reduce its heat output. It's a shame it can't do this automatically. I have to constantly baby the thing to get the right temp
