The Trane XL18i is a two-stage air conditioner with an efficiency rating of up to 18.00 SEER. The unit’s Climatuff compressor automatically adjusts itself to provide constant temperatures and quiet operation. An integrated fan with a blade-down design reduces sound levels while improving efficiency, and an aluminum coil resists corrosion while enhancing heat transfer. Full-sided galvanized steel louvered panels with a baked-on powder paint finish and zinc-coated fasteners protect the unit from weather hazards and corrosion, and a DuraTuff basepan is designed not to crack, warp or corrode.
