I have a large floor fan that fits nearly perfectly into a 20" sliding window in my bedroom. I have it set to push air out and crack a few windows open in the living room to get a nice breeze. It can cool the entire 1200 sqft condo -minus my roommates bedroom- to a few degrees of the outdoor temperature in around half a hour and there is even a significant inward draft that comes under our front door from the air-conditioned hallway outside
.
If the OP already has all his hardware -the 2 fans and AC unit- I would try to use the fans first to cool the place in the evenings either 1 in and other out or both out on the same window if possible. What tends to happen with this set up is the cooler air will flow from the open window(s) and ride along the ground like a river towards the fan and out so using the air conditioner in fan mode or low power AC to mix the air in the living room would help keep things cooler although another fan preferably a ceiling fan would work best. Another trick to induce turbulence in the air is to only open the other window and the sliding patio door a few inches instead of wide open allowing for a focused jet of cool outdoor air to mix with the warmer room air better. You can also do the same thing with the doors only opening them inch or to and using a doorstop(s) to hold them in place
Of course on hot days I would leave the AC on during the day and use a bathroom or kitchen fan on to pull the cool air around your place more and if it becomes unbearable in the afternoon or evening open up the windows and switch on the fans.
