Newer air conditioners can be subsidized by state energy offices or local utilities.


Usage Tips

  • Turn it down. If your unit has a thermostat, set it to 78 degrees F.
  • Fan only. At night, use your air conditioner's fan-only mode.
  • Use the recirculate option instead of constantly cooling hot air from outdoors.
  • Turn the air conditioner off when you're out.
  • Clean the filter often, (biweekly or as needed), and where possible, hose down the back of the unit to remove debris that can clog cooling coils.
  • Seal leaks. Make sure window models are installed as tightly as possible to prevent hot air from seeping in around the unit's edges.
