Used air conditioner units can be purchased online from stores such as the Used A/C Warehouse and Budget Heating & Air Conditioning, as well as from equipment auction sites such as Bid-on-Equipment. General auction sites such as eBay also frequently contain listings for used air conditioner units.
The Uses A/C Warehouse allows users to view its selection of used parts and units directly from its website. Users can conduct a search of its inventory using keywords or unit model numbers, as well as browse listings based on the size of the unit. Each listing contains a picture of the air conditioner, along with a description of its condition, a list of its features and details about its price. Users located in the Las Vegas, Nevada, area can also purchase an installation package from the company along with any air conditioner units.
Listings on eBay also contain picture of the unit along with a description of how much it was used and details about its features. Each item is sold either through a traditional auction model, in which users bid on the item over a set period of time, or through a standard immediate purchase model. Items sold through immediate purchase allow buyers to make offers on the item to the seller.
