What are the differences in Trane’s 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.
