Ruud, Trane, and American Standard are among the more reliable natural gas furnace brands, whereas Goodman, Lennox, and Amana are among the less reliable brands. York, however, stands out as the least reliable brand and cannot be recommended by Consumer Reports at this time. That’s what we found based on the feedback of 21,618 subscribers, who reported on their experiences with gas furnaces installed between 2011 and 2016.
