How much is an air conditioning unit?

In general, the cost of an air conditioning unit can range from as little as $150 for a small window unit to $20,000+ for a fully installed system of either central AC or a ductless split system. These costs can be broken down into two categories: the price of the air conditioning unit itself and the cost of installation. In addition, there are a variety of factors that impact the cost of the unit as well as installation costs.
