As of November 2015, the majority of reviews for Evcon air conditioners on FurnaceCompare.com are unfavourable. Customers allege that the products are unreliable and that warranty-expiring parts frequently fail. One of the 13 reviews says the item is recommended since it has a long shelf life.
One favourable reviewer mentions that their 19-year-old air conditioner was just replaced by a more efficient one. Reviews typically highlight how the devices only survive a few years and need expensive annual maintenance.
One component failed, according to a different customer, and even though the product was still covered by warranty, the repair bill came to $450.
