Fall Saver Tips

Summer Tips
  • Use ceiling fans to increase comfort level. Set your thermostat at 78°F or higher. For each degree you lower the temperature from the recommended setting, you can increase your bill up to 4%.
  • Don't place lamps or TV sets near your air conditioner thermostat. The thermostat senses heat from these appliances, which causes the air conditioning to run longer than necessary and use more energy.
  • Plant trees or shrubs to shade air conditioning units but not to block the airflow. A unit operating in the shade uses as much as 10% less electricity than the same one operating in the sun.
  • Install a programmable thermostat to adjust the temperature automatically and maximize energy savings. When cooling, try programming the thermostat to 82°F while you are gone in the daytime and return it to 78°F two hours before you get home.


Fall Saver Tips
Spring Tips
  • Use ENERGY STAR® labeled products. A new refrigerator with an ENERGY STAR label will save you between $35 and $70 a year compared to the models designed 15 years ago.
  • Install 14-watt compact fluorescent light bulbs in place of 60-watt incandescent bulbs. CFLs use at least 2/3 less energy than standard incandescent bulbs to provide the same amount of light, and last up to 10 times longer. You can save $30 or more in energy costs over each bulb’s lifetime.
  • The most important maintenance task that will ensure the efficiency of your air conditioner is to replace or clean filters monthly. Clogged, dirty filters block normal airflow and reduce a system's efficiency significantly.

Fall Tips
  • About 80-85% of the energy used for washing clothes is for heating the water. There are two ways to reduce the amount of energy used for washing clothes: use less water and use cold water. Your clothes will be just as clean as using warm or hot water and you'll save money by not heating the water. Costs are 26¢ per load using hot water and 11¢ per load using warm water.
  • Use natural gas for cooking, water heating and drying clothes. Natural gas can save up to 30% compared with electric appliances. GRU has natural gas rebates available.
  • Lower the thermostat on your hot water heater to 120°F. For each 10°F reduction in water temperature, you can save 3-5% in energy costs.

Fall Saver Tips
Winter Tips
  • Set your thermostat at 68°F or lower during the winter months. For each degree you increase the temperature from the recommended setting, you can increase your bill up to 4%.
  • Check your heating system's filters once a month and clean or replace as needed. Maintaining the system helps it to run longer while using less energy.
  • Weatherize your home. You can save 30% off heating costs by simply caulking, sealing and weather-stripping around all windows, outside doors or where plumbing, duct work and electrical wiring penetrate exterior walls, floors or ceilings.

Year 'Round Tips
  • Provide solar screens for east and west windows. Sunny windows can account for 10-25% of your cooling bill by making your air conditioner work 2-3 times harder.
  • You can save as much as 10% a year on your utility bill by simply turning your thermostat down during heating season, up during cooling season or off when you leave home for more than two hours.
  • If buying a new heating and air conditioning system, make sure it is sized properly. An air conditioner that's too large for your home can use more energy than necessary to cool your home. A properly sized system can save you $600 a year in heating and cooling.
  • Weatherization and caulking things such as windows and doors can save more than 30% off cooling and heating costs.
  • Insulate your water heater to save energy and money. For every 10°F you lower the temperature setting, you can reduce your bill 3-5%.
  • Don't use the "rinse hold" setting on your dishwasher for just a few soiled dishes. It uses 3-7 gallons of hot water each time you use it.
  • Let your dishes air dry. If you don't have an automatic air-dry switch, turn off the control knob after the final rinse and prop the door open a little so the dishes air dry.
  • About 80-85% of the energy used for washing clothes is for heating the water. There are two ways to reduce the amount of energy used for washing clothes: use less water and use cooler water. Wash clothes in cold water only. Your clothes will be just as clean as using warm or hot water and you'll save money by not heating the water.
  • Check door seals on refrigerators and freezers. Place a dollar bill in the door as you close it. If it does not hold firmly, the seal is worn and needs to be replaced. A refrigerator door that does not close tightly will increase heat gain and cause the refrigerator to run more.
  • Match pan size to element size when cooking. For small pans, use a small burner and for large pans use a large burner. Using the wrong sized element will cause you to use more energy to cook.
  • Use glass or ceramic pans when cooking in ovens. This will allow you to reduce the cooking temperature by 25 degrees while cooking your food just as quickly.
  • Use the garbage disposal sparingly. Compost instead and save gallons of water every time.
  • Clean your dryer's lint filter after each use. A clean dryer filter will allow your dryer to work more efficiently. Dryer filters full of lint will cause your dryer to work harder and longer and use more energy.
  • Check your pool filtering system for debris and leaks. This way the filter will not have to work long and hard to clean the pool.
  • Check your central air conditioning/heating system filter once a month, clean or replace as needed, and maintain the system so it will run longer and not use more energy than necessary.
  • Make sure your home is properly insulated in order to keep the conditioned AC/heat within the home for a longer period of time.
  • Install a programmable thermostat to adjust the temperature automatically and maximize energy savings. When cooling, try programming the thermostat to 82°F while you are gone in the daytime and return it to 78°F two hours before you get home.
