2018 Furnace Ratings by Brand
Updated: May 2, 2018
Furnace Ratings as Determined by Consumer Ratings
- Armstrong Air
- Aire Flo
- American Standard
When a homeowner searches for furnace ratings they typically want to know how other consumers rate the furnaces that they own. mandores.com has collected thousands of consumer reviews since we began collecting them in 2006. In addition to writing a long-form review, reviewers also rate each furnace model from 1 ("Very Unsatisfied") to 5 ("Very Satisfied"). The previous list ranks furnaces from best to worst.
We have collected reviews on more than 90 different brands of furnaces -- however, we have not included all those brands in the list above. If we have only collected a handful of reviews, we run the risk that a single homeowner might affect the average rating too far in one direction or another. For that reason, we have only included the average rating for brands that at least 25 consumers have reviewed. However, all of our furnace reviews are available here.
Brands with the Highest Fleet Efficiency
There is a second type of furnace rating -- a unit's efficiency rating. A warm-air furnace's efficiency rating is typically measured by its AFUE (Annual Fuel Utilization Efficiency). The "fleet efficiency" of a particular brand is the average efficiency of all of the models sold under that brand name.
Natural Gas Furnaces (with more than 100 models)
Natural Gas Furnaces (with 100 or fewer models)
Oil Furnaces (all brands)
Notes on Furnace Ratings
The "fleet efficiency" or "furnace rating" of a particular furnace brand indicates
nothing about furnace quality or furnace durability. In addition, although the fleet
efficiency of one brand might exceed that of another, this does not necessarily indicate that
any particular model of furnace marketed under the first brand out-performs
any particular model of furnace marketed under the second. To determine whether
one model outperforms another, simple compare the
AFUE of the two models.
