Good morning. Friday night everything seemed to be working but no air was coming from my vents to cool the house. The outside unit appeared to be functioning as well as the inside unit but the upper half of the inside unit was sweating and very cold. I turned it off and let it thaw and tried again with the same results. I had a company come in and check it out and he said my Acoil was leaking freon. They are supposed to call me with an estimate tomorrow but I was wondering what one could expect to pay for an Acoil? The outside unit is an XE1000, the inside unit is an XE80. It is 11 years old. Thanks.
