Think Cool Thoughts.

Here's something we want you to think about. Outside the mercury is rising, and the lazy, hazy days of summer are sizzling - even in the shade. But, inside, your home is perfectly comfortable. Perfectly cool. Perfectly Trane.

That's what our XL 1800 central air conditioning system can give you. Total comfort, all summer long.

The Highest Efficiency Around

And, we mean that. With a SEER rating of up to 18.00, the XL 1800 offers the unbeatable combination of energy efficiency and lower operating costs. SEER stands for Seasonal Energy Efficiency Ratio, a standard measurement of air conditioning efficiency established by the U.S. Department of Energy. The higher it is, the greater the efficiency.

Dual Compressors For Two-Stage Cooling.

In Addition to its high efficiency, there's something else unique about the XL 1800 air conditioner. It has side-by-side, dual Climatuff compressors that allow for two-stage cooling. That means that most of the time your unit will operate comfortably and efficiently at low speed, giving you increased savings.

And, because it operates at this low speed most of the time, you unit will run quietly at the highest comfort level. But, on those extremely hot days when more cooling is required, the XL 1800 will switch to the second stage to provide maximum comfort.

Enhanced Airflow Provides Greater Humidity Control.

When matched with a variable speed indoor unit from Trane, the XL 1800 has another special comfort feature. It's a method of enhancing airflow that we call Comfort-R and it gives you greater humidity control in cooling. This is accomplished by running the fan at a slower speed during start up. This managed cycle of cooling reduces temperature variance for the optimum in home comfort.
