For a great combination of Cost and Efficiency the Super Efficiency Air Conditioners from Trane such as the XL15i and XL15 are a real value with a SEER rating of 16.5 and 17.0. These two models include some of Trane’s quality features like a Climatuff compressor, Exclusive Spine Fin coil, and you can add Trane CleanEffects to your system for advanced air filtration that removes more dust, pollen and other irritants from conditioned air for a cleaner, healthier, more comfortable home.
The XR15 which has a SEER rating of up to 17.00 makes it an excellent choice for home comfort and for earning energy-efficiency tax credits and increased energy efficiency may substantially lower your home cooling costs. With a warranty of 12-years on compressor on the XL15i ( 10 years on the XL15), 10-year on outdoor coil, and 10-year on internal functional parts basic maintenance should be all that is required for at least that time. The following graph compares the Cost / Efficiency of both the XL15i and XL15 and compares them to the XL16i from their Ultra Efficiency Air Conditioner series.
