On extremely hot days, avoid setting your thermostat at a colder setting than normal. We advise a programmable thermostat to help you with the “SET IT AND LET IT” philosophy.
Your system will not cool your home any faster and can result in excessive stress on your system and unnecessary expense. For optimal savings set your thermostat to 78 degrees when you are home and 85 degrees or off when you are away. Most new AC units are designed to keep your home 20 degrees or so cooler than the temperature outside. If it’s 100 degrees outside, the optimal temperature setting in terms of efficiency is 78-80 degrees.
Programmable thermostats can help manage utility expenses.
Using ceiling or room fans allows you to set the thermostat higher because the air movement will cool the room.
