Space Cooling

  • Maintain fans and air conditioners so they’re running at the highest efficiency.
  • Use appropriately-sized air conditioning units for the area you’re trying to cool. Supplement your cooling system with fans that circulate the cool air. Focus cooling efforts on rooms you use frequently; don’t cool unused rooms or areas.
  • Look for the ENERGY STAR ratings when you’re shopping for a new air conditioner: Above 9 energy efficiency rating (EER) for room air conditioners and above 12 seasonal energy efficiency rating (SEER) for central air conditioning.
  • Seal and insulate air conditioning ducts.
  • Reduce your need for air conditioning by insulating your home and tightening window and door openings.
  • Close window coverings during the day to block out the sun.
