I have a Traen Model number 2TTB0036A1000AA. When I turn it on it cools for a couple of minute then it starts making a loud sound. It sounds like when the a/c belt of a car stops working or being forced. The sound gets so loud that I have to turn it off. The air that comes out when it starts making that sound is warm.. It is a 7 year old model

The description you used makes it sound like the fan motor is starting to lock up. Check that out since it seems the motor might need to be lubricated or in most cases replaced.
