The Infinity^® 98 furnace delivers precision comfort with Greenspeed intelligence. This is the most advanced Carrier^® furnace ever made. Its unique design innovations achieve unprecedented efficiency and quiet.

Greenspeed intelligence is created by pairing adaptable-speed technology with our Infinity control's intelligence. The unique, modulating gas valve of this unit, when managed by the Infinity control, allows it to literally adapt its output to the needs of the home. With tiny, 1% adjustments between 40 and 100% capacity, it gives the home only the amount of heating necessary.

This allows the furnace to operate longer at steadier, lower capacities, which ensures incredible energy efficiency and quiet operation with tighter temperature control than standard furnaces.

Variable-speed blower operation is a part of the Greenspeed equation while also enhancing other system components. It's the outstanding choice for potentially boosting air conditioning system efficiency and improving summer dehumidification.
