Thanks for all of the responses. I am in Tucson so I will not be able to take advantage of references to specific businesses. The warranty is poor. It has a 5 year parts and a 2 year labor. Of course, we are just outside the labor coverage! There was no warranty for replacement Freon. It is frustrating that I have to pay so much for them to find the warranteed part, and then be charged to replace the freon that was lost due to that defective part!!! It seems that a 25lb cylinder of freon is available online for $200 or so. I guess that an EPA certification is required for me to purchase that material myself?
