I'm surprised that your 30.1 came with a 13,500 BTU. I have a 2015 30.1 with a 15,000 BTU (it came as an upgrade) and it pushed quite cool air into the bedroom all three days last weekend at 93+ all day and 82-85 at night. When I was looking at the ACEs last year I thought they all came with the air at 15,000 and other standard upgrades.
The downside that I have with the air is that the gallons of water it pulls from the air at these temperatures streams right down on the screen door when the door is open.
All aside, I would think that the air conditioner should be able to put some cool air out and if it's putting out hot air --- something's wrong and if it's still in the one year warranty period Coleman/Thor should come to your aid.
