How cold should home air conditioner blow?

A home air conditioner should ideally blow air at a temperature between 20 to 25 degrees Fahrenheit cooler than the outside temperature. For optimal comfort, this usually translates to around 60 to 70 degrees Fahrenheit when set to cool mode. However, efficiency and comfort can vary based on humidity levels and individual preferences. It's important to ensure that the system is properly maintained for effective performance.
