How cool can I keep my house in the summer?

Newer homes are designed according to your the builder’s specs which require the home to maintain a temperature between 15-18 degrees cooler than the outdoor temperature. For example, if it is 95 degrees outside, your system has been designed to maintain a temperature of between 77 and 80 degrees inside your home. The lower you set your thermostat during the warmer months, the longer your system is going to have to run, thereby raising your electric bill.
