When matched with a variable speed indoor unit from Trane, the XL20i has another special 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. Comfort-R™ also provides warmer air during heating start-up. These managed cycles reduce temperature variances for the optimum in home comfort.

Efficient performance
The XL20i’s SEER (Seasonal Energy Efficiency Ratio) rating of up to 20.00 is among the highest energy efficiency rating of any air conditioner available today. The XL20i has two compressors: one for milder weather and a second larger compressor for those extremely hot days. It’s like having two units in one.

ComfortLink II Communicating Capability
ComfortLink II communicating technology (available when matched with communicating indoor units) connects all of your key components so your system automatically charges, configures and calibrates for optimal performance and efficiency through the lifetime of your products. When the optional Telephone Access Module (TAM) is added, you can conveniently adjust settings and receive system updates wherever you are by phone.

Economical operation
Increased efficiency may substantially lower your home cooling costs.

Quiet comfort
Multi-stage fan motor adjusts speed to quietly provide maximum comfort.

Durable construction
Materials for all components are tested again and again for long-lasting performance and durability.
