Air Conditioner and Heat Pump From Trane

  • By Katy Tomasulo

The XL 20i air conditioner/heat pump boasts 20-SEER efficiency and includes ComfortLink II with Charge Assist. ComfortLink II provides plug-and-play setup, requiring just two wires for installation and providing a digital interface for precise setup; ComfortLink II-enabled indoor and outdoor units communicate for automatic and proper charging, configuration, and calibration. The unit includes R410A refrigerant; dual compressors for two-stage heating and cooling; and an all-aluminum Spine Fin coil with low air resistance, greater heat exchanging capabilities, and more corrosion and leak resistance, the maker says. www.trane.com.
