text:  Do not turn it off during the day. Do not set it back a few degrees at night and think you can drop the temperature of your house when you get home or when you get up in the morning or something. Just set your thermostat to the temperature that you want your house to be and just leave it there. The system will monitor itself from there. As stated earlier, the home is absorbing heat from the sun and the air conditioning system is extracting the heat.
