Well, if the air blowing out of the AC (into the room) is rising 25 degrees,
then you very obviously have installed the unit upside down. turn it right
side up, and it will start cooling.
Hint: I've found that a fan blowing TOWARDS the AC cools the room better
than a fan blowing away from the AC.
"Across the coil" means air coming into the unit, and air blowing out. If
the tech support guys say rise, then they mean the outdoor air. Measure
temperature of the air sucking in the side of the AC, and the temperature of
the hot air dumping out the back. Is the hot air noticably hotter than the
air coming in the side?
