GUH 3 Ton 70,000 BTU 96% Gas Furnace, 2 Stage Variable Speed ECM

Since the blower motor accelerates slowly, the furnace delivers a gentle stream of warmth, so you always have air that feels just right coming out of your ducts. Slower acceleration and deceleration also allow for quieter operation, humidity control and greater energy efficiency.
The Comfort-Aire GUH96T furnace is as flexible as it is dependable. Two-stage operation allows it to adjust heat output based on the temperatures inside and outside your home, so you’re always using energy efficiently.
