Tips for Saving Money and Lowering Air Pollution

Install a programmable thermostat: Cooling and heating your home accounts for almost half of your energy bill – about $1,000 a year.
    • Set your thermostat for 78 degrees during summer — or 68 degrees during winter — when you are awake and at home.


    • Decide upon a period of eight hours or more each day to set your thermostat 10 − 15 degrees warmer during summer or 10 to 15 degrees cooler during the winter.

  Check your heating/cooling filter every month, particularly during winter and summer when the system may run almost constantly. Change the filter every three months or sooner.
  Dirty filters slow down air flow, making the system work harder to keep you comfortable.

  Turn off unnecessary lights and unused appliances to reduce emissions from power plants and save money. Purchase Energy Star® appliances.

  Minimize the amount of gasoline you use.
     • Walk, carpool, ride a bicycle and use mass transit.
     • Consolidate trips.
     • Avoid unnecessary idling. Park instead of using drive-through lanes. Turn off your engine while waiting to drop off or pick up people.
