Question:
OK…..we live in AZ and it has been about 112-114 for the past week so the a/c has been running a lot to keep the house at 80. On Friday, I was sitting on the couch watching a movie with the kids and it was a comfortable 80 degrees in the house. By the time the movie was over it was up to 86 degrees. My husband looked at the a/c and said it was frozen so we waited for it to defrost and started the a/c again last night and it got down to 85 degrees and now this morning it’s back up to 87 and the coils are frozen again. Any ideas/advice/suggestions to prevent this from happening?

Some of the time it lightly blows cold air (but not enough to cool it down any in the house) and others times no air at all.

One of two reasons why this is probably happening.
First, the airflow across the indoor coil is low. Due to either the filter or coil being blocked, cleaning these will fix that problem. Or the indoor fan or motor is not working properly.
Secondly, you may have a freon leak in the machine. If so then there is nothing you can do to fix it, you will need specialist help.
As suggested above, in some machines, mainly the window type, if they are run continuously over extended periods of time (I mean hours and hours) without cycling off then you may get ice forming on the indoor coil. This is also an indication that the machine is undersized and overworked.
Hope this helps.
