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 the top 10 central air conditioner series from best to worst, based on the average of those consumer satisfaction ratings.
FurnaceCompare.com has collected reviews on more than 50 different brands and 350 different series of central air conditioners. However, we have only included a series on this list if we have at least 5 reviews of that series, and if the series has not been discontinued. 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.
