A\C in apartment only spreads to living room

The air conditioner set in the wall is probably only intended for one room and is not intended for the whole apartment. Talk to your landlord and find out for sure. You may have to get another one to put in the bedroom or get an exhaust fan that pulls the warm air out and put in the bedroom. Have you thought about a dehumidifier?

Would your landlaord be willing to install a more powerful unit, or would he be averse to you doing so? You might argue this as a health and safety issue. Can't imagine it's doing your furniture any good.

you a fan to direct some of the cool air

Is the filter clean? Check that out or have landlord do that while you are home so that you can see it and how it's done.

When talking to my leasing lady initially she said the general “people like to use fans since a/c can only spread so far” which I took as that general blanket statement that people say about air conditioners. I didn’t think it would be THIS bad. Her saying that leads me to think that she “warned me” in her own way. Unfortunately when I toured and signed my lease it was chilly out so I didn’t really even have this issue.

Its a two story apartment but the heat makes it feel like those older houses where the downstairs is pretty cool but the upstairs feels like an attic sauna. Except my living room is the cool area and the rest of the apartment is the stuffy hot attic. It sucks!!! When it’s window and cool i get a great cross breeze. But it’s been a nasty 90+ degrees in Ohio lately. So wind is basically just heat being blown.

The heat and staleness adds on to the odors in the bathroom and kitchen cabinets. They just won’t go away. I think the heat and lack of air flow contribute to this.

If the unit is putting out "muggy" air... then it might be a swamp cooler... which only works if the humidity is below 15%... your only option, for the bedroom... might be a window unit.... especially if the landlord is adverse to upgrading the current set up.

This is not the best and energy efficient solution but it may get cool air into the rooms. Fans just push air around. You are just mixing cool air with the hot and tempering it. Put the fans in the windows with the windows open or at least against open windows in the rooms. You would be pulling the hot air out of the rooms and drawing the cool air into the rooms. You'd be creating a cross breeze. Once the rooms are cooler you can close the windows. It may not last long but it may help. Similar when turning the AC in a hot car. Crack the windows a little to force the hot air out and the car cools down quicker.

Sometimes air conditioners need cleaning, especially the filters, Mine worked two times better by simply washing the filter. And you are right, if the unit is big and old you can bet it is very stale and not healthy for you at all. PLEASE clean the filter right now. Mine slid right out, it was where the air slats are, the long ones that cover the whole front. I just washed it in hot soapy water It should be dry when you put it back in (use a hair dryer if you have to). Next find the size stated on or in the unit somewhere and you can find out if it's big enough to do the whole apartment or not. It probably did do the whole place when it was new. The newer ones are much better. My Dad bought a small $89 one at Aldi one summer and it cooled the whole downstairs of his big old house. Most small air conditioners have pull out sides to adjust to window sizes. But I would talk to your landlord. He should really be the one to take care of this problem for you. Good Luck.
