Product Information


The two-stage XL17i air conditioner offers up to 17.20 SEER2, providing efficient and reliable heating and cooling for your home. It is available in 2, 3, 4, and 5-ton models. This system features a Spine Fin™ coil, a swept fan blade, and a two-stage cooling Climatuff™ compressor, all protected by the durable WeatherGuard™ Top.

This system’s two-stage operation offers flexible comfort, ensuring your home remains comfortable year-round. Stage one operates at 67% of full capacity which extracts more humidity by extending run times. The all-aluminum Spine Fin™ condenser coil gives it the ability to cool every room to the right temperature efficiently. The XL17i is designed to withstand various climate conditions, making it a dependable choice for any homeowner seeking performance and durability.

This Trane XL17i air conditioner replaced the Trane XL18i model due to the SEER2 conversion in 2023. The features and efficiency of the Trane XL17i are largely identical with minor improvements, but the XL17i is rated using the DOE’s new method.

Our estimated price of the Trane XL17i air conditioner is $7,900 to $10,400 including installation. It’s important to note – providing exact pricing online is challenging due to the unique requirements of each home. The cost varies with the size of the unit and the complexity of the installation. A smaller unit like the 2-ton with properly installed ductwork will be more affordable, while larger units or complex installations will be on the higher end of the price spectrum.

Compatible Matching Furnaces

For optimal performance, the XL17i should be paired with compatible indoor equipment. We recommend the Trane Hyperion™ TAM9 Air Handler or Trane S9V2 Gas Furnace for seamless system operation and peak efficiency. The Hyperion™ TAM9 air handler is known for its variable speed capabilities, which enhance humidity control and overall comfort. The S9V2 gas furnaces provide high efficiency and compatibility with the XL17i for a seamless hybrid system. For an exact, personalized recommendation, consult with our experts.
