Trane's exclusive Comfort-R™ feature represents the ultimate in comfort. Most standard air handlers have only three fan speeds. Ours has twelve. The result? 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.

Since the air handler operates at slower speeds, air is drawn through your filters more gradually, allowing more thorough air cleaning.

Smart technology for better air
