AC is Not Working Well

The air co in our room is not working well. The room become a bit hot. I think I should call the guy from AC Repair Austin. Maybe the air co system need to be repair or get service since it was three months ago since we did it last time. I don't know when they can come to check the air co in our room. But let's hope that we can make appointment soon. We don't want to sleep in the hot room. And since there are too many mosquitoes in the night, we can't open the door or the window as well during the night. We will get too many mosquito bites in the end if we do that.
