Air Conditioning Energy Saving Tips

Posted 04-06-10 in Air Conditioning

With summer around the corner and warmer temperatures on the way, it’s good to know some ways to save energy and money and still stay “cool” this summer!

Energy Saving Tips:

  • If you are looking to replace your current central air conditioning system, look for a higher S.E.E.R. (seasonal energy efficiency ratio) system – 13 or better. A less efficient system will cost you more to run versus a higher S.E.E.R. system that will be more efficient and will pay for itself in a few years by reducing your electricity bills.
     
  • Make sure to have your central air conditioning system is serviced before the cooling season begins. This will ensure that it is running at its most efficient.
     
  • Replace air filters monthly. A dirty filter will reduce the efficiency of your system, making it run longer and harder and this increases the amount of energy needed to run your system. Keeping your filter clean can lower you energy consumption by 5%-15%.
     
  • Set your air conditioner’s thermostat as high as comfortable. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
     
  • Don’t set your thermostat at a colder temperature setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and unnecessary expense.
     
  • Set the fan speed on high except in very humid weather. When it’s humid set the fan speed on low – you’ll get better cooling.
     
  • Don’t place lamps or TV sets near your air conditioning thermostat. Your thermostat can sense heat from these appliances, and can cause the air conditioner to run longer than necessary.
     
  • Consider installing a programmable thermostat. This way you can vary the temperatures for when you are not at home or at night.
     
  • Consider ceiling fans to spread the cooled air more effectively through your home without greatly increasing your power use.
     
  • Reduce your cooling load by shading east and west windows. Also delay heat-generating activities, such as dishwashing or baking until the evening on hot days.
     
  • During the hottest days, keep the house closed tight during the day. Don’t let unwanted heat and humidity in.
     
  • Try not to use a dehumidifier at the same time your air conditioner is operating. The dehumidifier will increase the cooling load and force the air conditioner to work harder, which in turn increases your utility bill.
     
  • Make sure your air conditioning condenser unit is located in a shady spot with room to dispose of the heat it removes from your home. Don’t crowd it with shrubs or anything else.
     
  • Plant shade trees and shrubs around your house to help reduce the heat of the sun, especially on the sides. A unit operating in the shade uses as much as 10% less electricity than the same one operating in the sun.
