Bosch manufactures a full-line heating, cooling, and water heating portfolio spanning air-to-air and geothermal/water-source heat pumps, rooftop packaged and split systems, air handling units, condensing gas boilers and furnaces, and electric/hybrid water heaters. 

Their current lineup leans heavily into low-GWP refrigerant compliance and heat pump electrification, backed by connected controls for system-level integration.
