Q. What are the cost savings associated with thermostat settings?
A. An air conditioning thermostat set at 75 degrees would reflect an increase of 18 to 24 percent in cooling costs. A cost effective thermostat setting for heating is 70 degrees. You'll save 3 to 5 percent on your electric bill for each degree the thermostat is set below 70 degrees. Conversely, energy costs go up 3 to 5 percent for each degree set above 70 degrees.
