there are 3 main reasons that your a/c is blowing warm during a call for cooling they are 1.the electric resistance heater is on 2. the reversing valve is energized in a Heat Pump, or you are low on refrigerant
If the air flow is low, a primary filter or return register filters could be clogged, or your blower unit could have a faulty fan. If the air is warm then your condenser unit may need to be recharged/checked for leaks.

Chances are your air conditioner is low or out of coolant. You can go to AutoZone, Napa, Advance Auto, or numerous other do it yourself car repair stores and have it checked out.
Try getting it re-gassed? This must be done by a qualified aircon person. If this isn't the problem, they will probably tell you what it is.
blowing cool air, is the air only in your mouth... warm air comes from your lungs. temperature also varies by how open your mouth is while blowing air out
Blowing out "haaa" feels warm because it involves the mouth producing warm air from the lungs. On the other hand, blowing out "phooo" feels cool because it involves the process of evaporation of saliva from the mouth, which cools the air as it exits.
