In the summertime try setting your thermostat up a degree or 2 at a time until your body gets used to that temperature, keep doing that until you have increased the temperature inside by about 4 degrees. Your body will adjust to the temperature difference and so will your electric bill. In the wintertime never adjust your thermostat up by more than a degree at a time, by doing that you don’t allow your electric heaters to come on thus saving money and on those really cold days try setting your thermostat down a couple degrees. Remember your system is only designed to operate efficiently to a certain outside temperature after that your electric heaters will come on to help. By keeping the temperature lower, the unit doesn’t have to work as hard to maintain that level of comfort.
