Thermostat settings & efficiency.

Everyone's comfort level differs from one another. Most preferred air conditioning temperatures range from 70-74 F. The thermostat should never be set below 68 F as the freezing up of the air conditioning coil while most likely occur.

Also, as the outdoor ambient temperature rises, do not necessarily expect the indoor temperature to maintain more than a 15-20 F difference. This means that if the outdoor temperature is 95 F, expect the indoor temperature to range 75-80 F. We design the systems per the industry ASHRAE standard of 15-20 F temperature difference. Many systems may handle more of a temperature difference depending on the design & customer preference during the design phase.

The installation of programmable thermostats is a wise choice for energy efficiency. It is not necessary to keep your thermostat set to 70-72 F all day long while you are away from work to maintain a dehumidified & relatively cool house. You can set the daily program to ramp up the set temperature when you leave for work or wherever & have the setting drop within one-hour prior to arriving back home.

Also, it is recommended to keep the air conditioning system operating. If you shut the air conditioner down for the entire day while you are away, it will work that much harder @ the end of the day to remove the humidity & heat from inside your home. Similar to starting your vehicle, when the air conditioning system has to be started back up, that is when it uses the most energy & work. Setting the programmable thermostat is the preferred energy usage savings method.
