Are you on the road? We are parked in Oklahoma and we've had temps in the high 90s and our 13500 btu and 15000 btu a/c have handled the temps. But we never shut them down. We ensure that the inside never gets above 70 degrees and we always just let them run so the furniture and everything else is cold soaked as much as possible. Also helps the refer stay cold.
