Heating and Cooling


  1. Install a programmable thermostat and set your thermostat to adjust the temperature during the hours you’re not home.
  2. If you plan on being away from home for a week or more we do not recommend turning your air conditioner off completely; instead, set your thermostat to 82° F.
  3. Clean your air filters or replace them at least once per month.
  4. Using fans to create a cooling breeze will allow you to raise your thermostat setting and still keep your home comfortable in the summer months.
  5. Fans make the occupants feel cooler because they cause a wind-chill effect. Even though fans cost only a penny per hour to operate, it’s best to turn them off when you leave the room or house.
  6. During the summer, close your blinds or shades over windows facing south and west during the day to minimize the heat brought in by sunlight.
  7. Use white blinds or shades to deflect light away from your home.
  8. Stop air leaks by sealing, caulking, or weather stripping drafty windows and doors.
  9. Close fireplace dampers when not in use to prevent warm air from escaping.
  10. In the winter months, it’s best to set your thermostat to 70° F or lower. Each degree above 70° can increase your heating costs by as much as 3–5%.
  11. Lowering your energy usage is directly related to raising the setting on your thermostat. For every degree below the recommended 78° F, your cooling costs can increase to 5–7%. When you leave for work, raise your thermostat to around 81 to 82° and return it to 78° when you get home.
