Trane XL18i Central Air Conditioners

Trane XL18i Air Conditioner Overview

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.

Trane XL18i Air Conditioner Reviews

"Awesome System"

5.0 rating
Very Satisfied

Got an XL18i and it's been great. Wonderful installation crew made sure install was done right. Electric bill dropped by over $120 per month from my prior unit which was a 15 year old Rheem. Can't say enough good things: looks great, very quiet, no repairs and saving me big bucks. If anyone is having warranty issues you need to pick the right installer: it's likely there was an installation error.
