During the hot days of summer, the U.S. Weather Bureau publishes a "Heat
Index." This number tells us how hot the air feels. The Heat Index can be
higher than the actual temperature, because relative humidity has a lot to
do with our comfort. A Trane Comfort System can control
the humidity in your home, allowing you to set your thermostat higher and
still be comfortable. And statistics show that you could save 6-8% in
cooling costs for every degree you set thermostat above 78°F.
