because it is broken
The fan is not working.
warm air, the heat is what is being taken out of the inside of the house.
Car not blowing air or heat
I suppose when you say " the air stops blowing but the unit is still running" you mean the air that is blowing is not cool. If so, then the thermostat is faulty or needs to be set a lower temperature setting. If the unit blows cool for a few minutes and not cool for a few minutes, then cool again, etc. (called short-cycling), the unit is low on freon.
rear air unit has a air blending door solenoid, and is probably out. or broken making a clicking noise
Turn it on high
What do you mean by "has no heat"? No air blowing out, blowing out cold air when heater is on, blowing nothing at all? Heater not turning on? What specifically is happening?
because no matter waht temp. the air is, air wipes of the body heat from your skin so you will be cool
It may seem obvious, but it can happen. As you were setting the thermostat, you could have flicked the selector switch over to "heat" instead of "cool." If this happened, then the reason you feel the hot air blowing from your system is because the heat is on. Simply move the switch to the "cool" setting to start chilling out. Check the outside unit. This is where your compressor and condenser coils are located. Make sure the outside power switch is turned on to power the compressor. Without power, the system might run from the inside air handler, but it will not cool. Also check to see if there is debris such as leaves or other items blocking the air intakes on the system. This also can prevent proper cooling. Checking for airflow restrictions around the outside unit should be a regular maintenance routine.
Well, the air conditioning system draws the heat out of the passenger cabin, transfers the heat to the refrigerant, superheats the refrigerant, then rapidly transfers the heat from the superheated refrigerant to the ambient air which flows through the condenser fins. This removes heat from the refrigerant, causing it to cool rapidly and drastically, and that cool refrigerant returns to the evaporator, where the blower fan blows over the evaporator, blowing the cooled air into the passenger compartment.
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
If there is not a steady stream of cool air blowing over the motor and heating coil and removing heat from them, they will instantly burn out. (Been there. Done that.)
