If you set your AC temperature higher than the temperature outside, the air conditioner will not turn on or operate. This is because the AC system is designed to cool the indoor air to a temperature lower than the ambient temperature. When you set the AC temperature higher than the outdoor temperature, you are essentially telling the system that cooling is not required.
In most cases, people set their AC temperature lower than the outside temperature to create a comfortable indoor environment by cooling the air. The AC unit works by extracting heat from the indoor air and expelling it outside, which results in a lower temperature indoors. If you set the AC temperature higher than the outdoor temperature, the system will not engage the cooling cycle, and the indoor temperature will remain at the ambient level.
It's worth noting that running an AC system when it's unnecessary or setting it to extremely low temperatures can result in energy wastage and higher utility bills. It's generally recommended to set your AC temperature to a comfortable level that balances your comfort and energy efficiency.
