The line’s Greenspeed intelligence combines modulating and variable-speed technologies with a communicating control system to constantly adapt to a home’s conditions. The algorithm was designed specifically for variable-speed products, said Chris Nelson, VP of sales and marketing. It works as a system, not as components.

This is also the quietest gas furnace Carrier said it has ever built. In low-fire mode, where the furnace operates most of the time, sound ratings are as low as 38.4 db, which is less than the sound of a refrigerator.
