Infinity® 24 Heat Pump With GreenspeedMC Intelligence by Carrier®

The Infinity 24 heat pump with Greenspeed intelligence takes Carrier’s most advanced technology to the next level. Greenspeed intelligence is created by pairing adaptable-speed technology with the Infinity® System Control. 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 or heating 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.
