Evcon air conditioners receive mostly negative reviews on FurnaceCompare.com, as of November 2015. Customers complain that the units are not reliable and parts break shortly after the warranty expires. One of 13 reviewers recommends the product saying it has lasted for years.
One positive review notes that the air conditioner unit they owned lasted for 19 years and was just being replaced by a more efficient unit. Mostly, reviews point out that the units only last a few years and require high annual maintenance. Another consumer notes that one component broke, and even though the unit was still under warranty, it cost them $450 to repair.
