Unit does not cool correctly.
You can achieve the most effective and
economical cooling comfort if room has not
yet been heated up. Air Conditioner operates
more effectively if room temperature has
not raised and has been kept steady. To
drastically cool the air in a very hot room
requires much more time and energy.
