The fan motor inside Trane’s variable-speed air handler is designed to vary its speed based on your home’s heating and cooling requirements. That’s the beauty of the variable-speed technology – when matched with any of Trane’s Xli series of outdoor units, it gives you a reliable, consistent level of quiet comfort and saves energy in the process.
The Comfort-R™ difference
Trane’s exclusive Comfort-R™ feature represents the ultimate in comfort and provides more consistent temperatures, greater humidity control and better air heating.
Special insulation, door gaskets and thermal seals effectively seal in conditioned air, increasing efficiency and reducing your heating and cooling costs.
More speeds mean your air handler operates at the lowest effective speed much of the time.
