Sound Ratings

The sound ratings are measured in decibels -- the lower the decibels, the quieter the air conditioner. The actual number of decibels produced by an air conditioner is a function of both its capacity (how many BTUs of cooling it generates) and the other components to which it is connected (such as a furnace or air handler used to distribute the cold air). In general, when you see a range, the lowest number of decibels is for the units with the smallest capacity that are paired with quiet components.

Average Pricing

There are two different types of prices shown in the "Average Pricing" column.

  • If you see a simple price, that is the average price that we found on the websites of internet retailers that sell that particular series of air conditioner.
  • If you see a price followed by the note (installed), this means that retailers are under agreement with the manufacturer not to publicly display the price of the units. In these cases, the price is an average of quotes given to different homeowners.

Note that prices -- even when they are published online -- can vary substantially based on the capacity of the unit in question: 24,000 BTU units are typically cheaper than 60,000 BTU units of the same brand and series.

The "installed" prices can vary even more dramatically. Not only do they cover a range of capacities, but prices also vary geographically and from installer to installer.

Compare our 2015 ratings to the best air conditioners of 2014.


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 bottom to top, based on the average of those consumer satisfaction ratings.

FurnaceCompare.com has collected reviews on more than 60 different brands and 500 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.
