No. The thermostat is not likely to be the cause.
It is broken. AC's usually blow cold air.

refill the a/c, it will blow hot air with no refrigerant in the vehicle.
If the AC is on Vent and it blows hot air in and the temp is at coolest. I think it does not matter because when you have it in vent it is venting air from the out side, it will start blowing air from the out side meaning if its hot out side the air will come out hot. Sometimes a car might blow hot air when you have it on full AC and cooldest. When you accelerate your car hard but it should cool down after you stop accelerating hard.
