Used gas furnaces can be purchased online through specialty heating and cooling unit resellers such as Used A/C Warehouse and Access Used Furnaces, as well as through auction sites such as eBay. Used gas furnaces are also sometimes sold by general used equipment resellers such as the Aaron Equipment Company.
The Aaron Equipment Company features a rotating selection of used equipment of various types, including different styles of furnaces. Each listing contains a picture of the unit as well as a detailed description of its condition and available features. Users are able to select multiple listings within the same category and cross compare features. In order to obtain pricing information, users must submit a request to receive a quote from a member of the Aaron Equipment Company's staff.
As eBay is used by many private sellers and small businesses without reliable or consistent access to supply from a manufacturer, customers may not always be able to find the exact model or type of furnace for which they are looking. To compensate for this, eBay allows users to create customized searched with the ability to send the user a notification whenever a newly listed item matches that search. Users are then able to take action on that item if desired.
