The Infinity 26 air conditioner with Greenspeed intelligence takes Carrier’s most advanced technology to the next level. If it looks like next-gen technology, that's becasue it is. This energy-efficient AC unit offers enhanced cooling, extra energy efficiency and ultra-quiet comfort where it matters most -- in your home. 

Greenspeed intelligence is created by pairing adaptable-speed technology with the Infinity® System Control.1 The unique, variable-speed compressor of this unit, allows it to literally adapt its output to the needs of the home. With infinite adjustments between 25 and 100% capacity, it gives the home only the amount of cooling necessary. 

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