- Set the thermostat as high as comfort will permit.
- Make sure attics are adequately ventilated to relieve heat buildup. If necessary, improve airflow by adding or enlarging vents.
- When building a new house or renovating an old one, choose light-colored roof shingles to reflect more of the sun's heat.
- During moderate weather, don't use the air conditioner unnecessarily.
- Draw blinds or drapes to block the sunlight during the hottest part of the day.
- Install awnings over windows exposed to direct sunlight.
- In the cooling season, don't run kitchen and bath exhaust fans longer than necessary.
- Don't place lamps, TV sets or other heat-producing devices beneath a wall-mounted thermostat. Rising heat from that equipment may cause the air conditioning system to overcool your house.
