I have had to turn on my AC in the past few days. I am noticing that it has been running all day every day and the house is still pretty hot. I went out side and noticed that the insulation around the line running into my house needs to be replaced. In the spots where there is no insulation a thick layer of ice has formed. (I tried attaching a picture, but it was too large of a file). I think that the lack of insulation would tend to create a place for the cold energy to dissipate out into the air outside rather than into the house, but I'm not sure. So I guess what im asking is does anybody think that replacing this would make the ac in the house feel colder? I am going to replace it anyway but I wonder if there is a bigger problem.
