Carrier heat pumps are air conditioners that can also heat your home

The Advanced Carrier Infinity™ Series heat pump offers the highest efficiency, and their Performance™ and Comfort™ Series heat pumps provide economical comfort.  Plus, add a Carrier gas furnace and enjoy additional heating in what they call "Hybrid Heat" as the most cost-savings system you can buy.
