I've seen this topic a few times on this forum but due to hijacked threads I'm not sure there was an answer.
I just moved into a new apartment. Brand new, never been lived in before. This is pretty much a sure bet that all the windows, weatherstripping and insulation are good.
The Air handler is located in the attic along with all the ducts. The compressor is located outside.
The compressor is a Goodman Model # CPLE24-1C.
I have a 1350 sq ft aparment.
The problem is that the A/C literally almost never shuts off. I have it set at 68 degrees. By about 3 in the morning it finally gets to 68 and shuts off. By noon the temperature outside gets to 90 and the inside temperature keeps rising up to about 80-82. Once the sun goes down the internal temperature slowly drops back down to 68.
I called the landlord who called the A/C guy who came and gave me a what I think is a line of crap. He tells me that 68 is ridiculous that I should set it at no lower than 75. I told him that even 75 is a moot point because it won't go lower than 80 in the apartment during the day. He went up into the attic to look at the air handler. He says everything is fine there. Checked the freon. He says it's good there. He told me that I'm going to just have to live with the fact that on a 90 degree day it's not going to get down to 68 degrees. I told him that it's not even getting down to 75. He told me that noone else in the complex is complaining. Everything up in the attic is fine, the freon is fine and I pretty much need to quit complaining. Well I am going to complain. I moved in 3 days ago and the A/C has practically never shut off. I have it set at 68, but it rarely even drops below 70 in the apartment.
Now here is my theory from reading some of the posts on this great site. I think it might be a duct problem. During the night the air blowing from the vents is semi-cool. During the day the air blowing from the vents is room temp. Every vent seems to be blowing a different temperature. One vent is barely blowing anything. Keep in mind that I know very little of A/C, but does this sound like a ton of leaks in the system?
I am very concerned because this new place costs $200 more a month in rent than my old place which I can barely afford. I don't want to even think about the power bill. I bought a window air conditioner for now before I consider what I'm going to do next. I know that the A/C guy that came here told the landlord I was nuts. But I think he is trying to avoid going into the 130 degree attic to do some ductwork while the work is still under warranty I assume.
What do you experts think? I'm sweaty and at my wits end.
