Hello, thank you for reading my post. I am a homeowner trying to help my AC man fix my AC problem. He's very bright, but the nature of my AC problem has left us both baffled.
A few weeks ago, my AC began to act up (the air in the house was not cooling down). He came by and advised my AC was low and filled it up. He inspected several things such as my filter and the attic fan - he said they were good. The AC seemed to work fine for 2 days, but then began to work on and off. Sometimes it works perfect and cools the air all day and sometimes it is on all day, but does not cool the air.
I called him again, but it was working when he came by. Well, it stopped blowing cold again that night. I went outside and the outside AC fan was not on - the fan in my attic was going and the vents were sending out uncooled air, but the outside fan was not doing anything. It stayed this way all night and I called him the next day and shared this information with him, but by the time he came by the following afternoon, everything was working normal.
He has come by three times now and each time he was here, the AC was working just fine. He hasn't asked for any service fees although I have offered to pay him for coming by.
He has told me he can not diagnose the problem if it is not in the 'failed condition'. I have used the same AC man here in TX and trust him, so I would like to keep going to him.
Before I call him (a 4th time!) and waste his time, is there anything I can look for to give him clues when the AC is not working right? It has been two weeks now with this on and off operating AC system and I wish it would just break or behave normally. There is a second AC system in this house (thankfully) and it works fine - it is the same age as the other AC, about 9 years old.
