Who is the parent company of Amana appliances?

The parent company of Amana appliances depends on whether you mean Amana home appliances like refrigerators and washers or Amana HVAC heating and cooling equipment, as they have different owners. For Amana home appliances including refrigerators, freezers, washers, dryers, dishwashers, and ranges, the parent company is Whirlpool Corporation, which is headquartered in Benton Harbor, Michigan, and is one of the largest appliance manufacturers in the world owning Whirlpool, Maytag, KitchenAid, and Amana brands.
