Used air conditioner units are frequently sold through specialty discount appliance websites, such as Budget Heating & Air Conditioning, as well as through online auction websites, such as eBay. Some used air conditioner units can also be found through classifieds sites, such as Craigslist.
The quality of information included in eBay listings for used air conditioning units varies from seller to seller, so it is important for buyers to obtain a solid understanding of the item and the seller before making a purchase. If a seller does not include pictures of the unit, or does not specify the exact condition of the unit, it may be beneficial for the user to contact the seller and inquire about the omitted information. Buyers can also use eBay's seller rating system to see if other customers have dealt with similar issues from that seller.
Craigslist does not require users to sign up for an account to create listings on the site, which means there is no way to judge the trustworthiness of a seller prior to making a purchase. The company suggests that buyers always meet in open, public areas for safety purposes and avoid giving the seller any personal or financial information before receiving the item.
