Consumers and homeowners have submitted thousands of reviews to this site. In addition to reviewing a particular model of equipment, the reviewer also assigns a rating from 1 (“Very Unsatisfied”) to 5 (“Very Satisfied”). The following list ranks central air conditioners from best to worst, based on the average of those consumer satisfaction ratings.

While we have collected reviews on nearly 70 different brands of air conditioners, we have not included all those brands above. If we only have a few reviews, there is a risk that a single homeowner will skew 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 central air conditioner reviews are available here.
Brands with the Highest Fleet Efficiency
A residential central air conditioner’s rating is typically measured by its SEER (Seasonal Energy Efficiency Rating). Commercial air conditioning efficiency is often measured by EER (Energy Efficiency Rating) rather than SEER. The “fleet efficiency” of a particular brand is the average efficiency of all of the models sold under that brand name.

Notes on Air Conditioner Ratings
Models without a recorded SEER have been excluded.
The “fleet efficiency” or “air conditioner rating” of a particular brand indicates nothing about air conditioner quality or air conditioner 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 air conditioner marketed under the first brand out-performs any particular model of air conditioner marketed under the second. To determine whether one model outperforms another, simple compare the SEER of the two models.
