I am being told that, depending on what I have the temperature set at, the ac unit will blow at a temp that is more or less cool. I am not in agreeance with this. What I have always understood was, the ac unit blows at "one" cool temp, and if the fan is set on "auto", the thermostat will shut the ac off once the room reaches the temp you have set it to. If the fan is set on "on", the ac will blow nonstop regardless of what the temp is set to. Am I mistaken or can I stuff a sock in my advisors mouth?

Ill try to make it as clear as possible.
Lets look at the components of an AC system
The compressor which cycles the coolant through the coils. It is either on or off.
The thermostat switch is a temperature sensing switch. It turns the compressor on when the return (the air coming back into the ac) temeperature rises above the set temperature.
The fan control switch which controls the speed of the blower fan.
Now lets look at how they all work together.
Lets say you have the thermostat set to 21degrees C (69.8F). The compressor will keep running until the room temperature reaches 21C. Once the set temperature is reached the compressor will shut down until the temperature goes over 21C again. Thats why the noise of an AC changes.
Now about the Fan setting. Normally there are 4 fan settings. Hi, Mid, Low and Auto.
The manual settings (hi,mid, low) stay the same once you set them. They dont get affected by the temperature and just keep blowing at the set speed.
The auto setting runs in conjunction with the thermostat. If the room temperature is much higher than the set temperature the fan will run at a higher speed. Once the temperature drops to the desired temperature, the fan speed will drop to lower speeds to reduce noise and electrical consumption.
I hope i made sense.
If you have any further questions don't hesitate to contact me.

No that adviser is not correct.
The air is cooled down a certain number of degrees from what the incoming air is at. The setting is what you hope that the cooling air will make the room become. If that you pick a very cold setting then the cooled air has to blow for a long time. If it you pick not very cold then the cooled air will shut off sooner. If it is very hot and the air conditioner is not strong enough for that cooling to achieve the thermostat temperature the air conditioner will run continuously without the room being where you want it. The shut-off and turn-on are what the thermostat is doing. The thermostat is not modulating the coolness of the air coming out of the air conditioner.
Get a sock ready for that advisor.

I'll let you answer the sock question but here is how central air works.
The thermostat has to be "calling" (set higher or lower than it is in the room). If the stat is set to auto then the FAN will only run when the stat is calling. The air temperature for cooling will be around 50 degrees or so and for heating about 90 something.
The stat doesn't change the temperature of the air going in the room it just tells the unit to run until it is satisfied.
If the stat is set to ON then the fan will never turn off even if there is not heat or cool air needed.
Summary. Fan ON/AUTO = circulates air in room/s. Temperature setting = calls for cool or heat

On average, an air conditioner will deliver air about 8 - 15 degrees farenheit coller than the air that it pulls in from the room (assuming the unit is big enough to handle the area in question.). Once the temperature at the thermostat or thermostat probe reaches the preset, it shuts the unit off.

You are correct. It doesn't matter what you set the thermostat on, the air coming from the vents will be the same temperature. It will continue running until the room temperature reaches what the thermostat is set at. However, If you have it set to "on", the fan will run non-stop, but the compressor will still cycle on and off based on the thermostat setting.

Yes .you are right but.The fan has setting : hi;medium; lo; fan speed.
The compressor will be thermostat /temp.control to cut in and cut off. as per setting.irrespective of fan speed
The latest inverter type air con is more energy efficient that work with speed n temp control for the compressor's motor
ps use a hanker chief,your stock stinks HaHaHa

your ac unit puts out roughly the same temp of air, depending on outside conditions. set your stat for the temp u desire and forget about it. the room will come to the temp u set.

No, they have to blow a relatively small volume at a temperature below the setting, in order to reduce the temperature of the large volume of the house.

Im not married but my brother loves turning the heater up super high and one time he set it at 95 and left for school and the heat woke me up..i wanted to kill him i was dying. Why don't you guys try to agree on a Temperature like 70?
