If it is 100 degrees outside, it is recommended that you set your home to 75-80 degrees or higher. Most air conditioning systems can only maintain a 20 degree difference between the temperature outside and the temperature inside. When it is 100 degrees or more outside, your air conditioning system will be working at its max to keep your home cool. To minimize the load on your AC unit, you should close your blinds and implement other ways to reduce the temperature inside your home naturally.
