An 8000 btu air conditioner can work great for a big living room on the shady side of the house. But put it in an upstairs room with sun streaming in from 4 windows and it won't keep up. Remember A/C's perform two functions they COOL and DEHUMIDIFY the air. If you think bigger is better its not, too large an A/C unit in a room will get it cool, but it will feel "clammy", because the unit will turn off before it's had sufficient run-time to dehumidify the room. It should say on the box what room size it's for. 5000 would cover an average bedroom. 18000 would do your whole apartment. Any of the major brands these days make decent units. Keep it clean, and it'll last for years. It depends on the size of the rooms and how much heat-load they are subject to.

I would find out from the manufacture how the unit disposes of the moisture it captures from the room. As this moisture being removed from the air is what helps your skin cool off. If the unit just evaporates the water back into the room, as a refrigerator does, you will not be happy with the cooling. Hope this helps.

Also, if you happen to get caught by the EPA doing this you can serve up to ten years in a federal prison along with a $32,000.00 per offense, per day.

Air conditioning is not putting cold air into a space, it is removing the heat and moisture. Therefore the heat that is removed needs to be released somewhere, ideally outside. If you are pumping hot discharge air from your air conditioner into a hot attic, you will have problems. You want to dump that heat outside. If you are concerned about security why don't you extend the discharge hose through the attic and discharge it through an attic window instead. If there is no attic window I would assume that you may have an attic roof vent. If you could direct it through a roof vent in the attic, that may work fine. You can look at my link below and see how we diverted an exhaust hood from a microwave oven that had a range exhaust fan in it. The existing pipe just terminated into the attic, not all the way to the outside. We continued the vent through the attic to a roof vent in the attic. The inspector then passed it. I chose to use the existing roof vent which was almost directly above the kitchen Range hood, rather than cutting a new hole in the existing roof. You can see before and after photos to see what we did.
