The Trane XL20i heat pump has two compressors: one for milder weather and a second larger compressor for extremely hot days. According to the company, it’s like having two units in one. When matched with a variable-speed indoor unit from Trane, the XL20i has another special feature; it’s a method of enhancing airflow the company calls Comfort-R™. It provides greater humidity control in cooling, which 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.
