I've lived in my condo for 2 years. Had new air handler/ furnace installed in 2009 right after I moved in and it cost me $. Last May 2010 had compressor replaced. Work was contracted through American Home Shield Home Warranty. Now compressor has konked out, warranty was for one year so it expired in May 2011. It must have been a piece of junk to only last one year. I've had ARS out here - service and sales. Do I buy an R22 unit for the roof to just fix the AC or tear out the brand new air handler/furnace to accomodate a R410A AC unit? $. Helpless. I don't know what to do. Thanks.
