What are the differences in Tranes XB and XL heat pump and air conditioner units?
Our XL outdoor product line has a higher cooling efficiency (SEER) range than the XB line. Some of the enhanced features include Trane’s patented WeatherGuard top that provides maximum protection for the outdoor condenser coil from environmental conditions, a compressor sound enclosure for quiet performance, a two-speed condenser fan that improves both efficiency and sound levels, and twice the original limited warranty as the XB outdoor product line.
