I've got a cooling issue. I have an indoor unit that has ran fine for years. Recently I haven't been able to cool the house below 78 degrees. I replaced the filter, the air is blowing out great (as I just replaced the outside unit) it's 58-60 degrees. The attic is 115 degrees (the temp outside is about 100 degrees during the day) I checked the ducts, there are two I can see, they are fine, however I have a dropped ceiling in the middle of the house that the 6 other ducts run through. Inside this "pocket" it is about 98 degrees (I found a hole in the attic sheetrock). Replaced the air filter, and I had a guy out 3 weeks ago and my freon level was excellent. Any idea what my problem may be? I'm a little puzzled on this one. Any help is much appreciated!
