The air outside is actually cooler at night, so you are needing the a/c in cooler conditions. Unless, your condo is trapping hot air inside in the evening which does happen, esp in older condo's with thick walls.
You need to open those windows and let the cool evening air inside! Use a fan like before said and circulate the cool air. Not pump a/c into a condo that has trapped hot air inside from the daytime.
You will have to run the a/c all night to get that warm air out with no windows open for it to escape 🤣
I think you are falling for the idea that a/c works well in a hot tropical climate. It does not, really, unless you force it on all the time and just don't give a hoot about the cost.
