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.
The following chart shows the estimated breakdown rates for gas furnaces might affect reliability. Still, choosing a gas furnace from a more dependable brand can improve your odds of getting a reliable model.
Due to a change in our methodology, our reliability estimates are not comparable to previous years. In the past, our estimates were based on instances of repair or serious problems. We now base our estimates on the rate at which gas furnaces break down or stop functioning well enough to sufficiently heat a home.
