What is the average cost of an Air Conditioner in 2010? AC Unit Price Range

Having the right air conditioner can really help you stay sane in hot weather. At the same time, they can cost a bundle. A small window air conditioning unit can cost as little as $100 or as much as $500. A central air AC system generally costs between $3,000 and $6,000, including installation, if your house has existing air ducts. If air ducts are not present and the installers are required to alter the house structure and create these ducts, the price can easily break $10,000.
