FEATURES YOU’LL WANT TO
KNOW MORE ABOUT
Comfort-R™ Comfort Enhancement
System
Comfort can best be described as the proper balance
of temperature and relative humidity, also known as
“your comfort index.” The greatest level of comfort is
achieved when the temperature and relative humidity
are in balance with your body. When the relative
humidity is low, you feel comfortable at a higher
temperature. Likewise, when the relative humidity is
high, you feel comfortable only at a lower tempera-
ture. However, if the relative humidity becomes too
high, then true comfort cannot be achieved at any
temperature.
The Comfort-R™ system is specifically designed to
enhance the moisture removal process of your air
conditioning system and to make the air drier. This
system is so unique, it received a patent from the U.S.
Patent Office. During times of high relative humidity,
as well as during mild weather, the Comfort-R system
increases the moisture removal ability of your air-
conditioning system. This results in a lower relative
humidity inside your home, which in turn, allows you
to feel more comfortable. The resulting lower relative
humidity also allows you to maintain the temperature
setting on your thermostat at a higher temperature.
