Consumer Reports lists American Standard, Bryant, Carrier, Lennox and Rheem furnaces as among the top-rated furnaces, as of September 2014. The manufacturer websites for these furnaces direct consumers to local heating, venting and air conditioning dealers and contractors for purchase and installation.
Consumer Reports, which also includes Trane furnaces in its list of top-rated gas furnaces, found no significant differences in repair records of the top six brands. In addition to local HVAC dealers, many of these furnaces are available for purchase on eBay, with many furnace purchases also including installation and manufacturer's warranty. EBay also carries many parts needed for repair of the top-rated gas furnaces.
