I moved into a different apartment a couple days ago and was looking for a little advice regarding its a/c.
The apartment is 600ish square feet and in a '60s building so likely not too well insulated by any means. The windows are large, and seem to be two layers of single-pane construction, so they are far from tight.
The a/c in question is a wall-mount unit in the corner of the living room. It's a GE unit from the mid 2000s by what I can gather by googling (no visible model number). It looks like either of the following... a AJCH10DCB or an AJCH12DCB which are either 9,900 or 11,600 BTU (respectively). It's supposed to be rated around 9.5 EER. It's a 220v and 15amp unit based on the two horizontal prongs on the plug. The filter was reasonably clean.
The issue is that it hasn't come close to catching up despite being on for several days. (The room was in the upper 70s when I moved in.) It's been set to the highest fan setting and the coldest temperature, and the lowest it's been able to reach is 72F (measured across the room). Naturally, that means that it hasn't cycled once, and the point at which the mechanical thermostat clicks off is about the 1/3 mark from MIN COOL to MAX COOL (that is, there's 2/3 of the scale where the thermostat does nothing since it can't catch up). The high today was 85F or so, and it was only able to hold 72F while I was at work with the blinds pulled, and lights and appliances off.
I'm not saying that 72F is unacceptably warm or anything, but the behavior seems strange and it certainly can't be efficient running it 24/7/365 to keep merely a ten or twelve degree differential over the outside. Even last night, with the low being around 60F, it couldn't catch up or cool the room below 72 despite being set to the max cool setting. This seems much worse than my counter-example of a comparable window a/c I've used, which could easily freeze out a similar-size room if set to its lowest setting for that long, and could easily catch up and cycle at a normal setting.
Does this behavior seem normal? I'm expecting a big electric bill based on the fact that it hasn't cycled once or been able to catch up. It's also not a good sign for how it might work when the temps climb higher than 85 or so. (The climate is southern Wisconsin, so not hot, but it'll get plenty warm.)
Here's the unit (or a similar one), for reference: https://www.geappliances.com/appliance/GE-230-208-Volt-Built-In-Room-Air-Cool-Unit-AJCH10DCB
