The ac will turn on when the HVAC is in defrost mode, no matter what the temp is set at.
Typically it is more efficient (and cheaper) to use a set back thermostat. Here is the most basic reason. The rate at which heat is gained or lost by a home or building depends on the difference in temperature between the indoors and the outdoors. Setting the temperature back (higher in the summer and lower in the winter) decreases this temperature difference and thus the total amount of heat gained or lost by the building. When you raise your AC thermostat during the day when no one is home and then cool the house back down in the evening, the total amount of heat removed by the AC during this cycle is less then if you left it cool for the entire time.
In numbers, the most common sources of an AC voltage are the antennas of radios and TVs that are receiving radio signals. The next most common are electronic circuits that are oscillating, either by design or by accident. The least common are AC generators, such as the 'alternators' in cars and trucks, and the utilities' power generating stations.

On most vehicles, it only runs when the temperature is high enough or the ac requires it.On most vehicles, it only runs when the temperature is high enough or the ac requires it.
Ideal temperature? Well if its the summer time no AC, just open up the windows and if its winter keep the heat on at least 60.
That's the entire point of an AC unit. it's to keep your house at a steady temperature
Ac oil helps to keep the gaskets in the ac system from drying out. The oil can be added separately or can be bought mixed into Freon from the store. Most importantly the oil lubricates the ac compressor, the only moving part in the ac system.
the ac in the car cools, the fact you have set a higher temperature than the ambient tempereature means that the car's heater is working and so is the ac, if you wish to heat up your car, turn the ac off.
The Auto button will turn on the AC then set your desired temperature.

The temperature sensor for your cooling fan may need to be changed. The temperature sensor wiring may need to be cleaned or replaced.

Usually, on most cars, this means that the weather is cool or that there is insufficient refrigerant in the system. It can also be caused by a restriction in the AC system or high temperature or excessive amount of refrigerant in the system.
