Why go to the movies when you can stay cool and comfortable at home?  If excess heat and humidity are making you feel uncomfortable, try an energy-efficient air conditioner.  You'll feel better and breathe more easily.

Cool wisely.  Follow these guidelines for efficient cooling of your home. 

• Cool only the rooms you are using by placing an energy-efficient air conditioner where you need it most.
• Use the right sized air conditioner for the area you are cooling (see table below).  
• Use ceiling fans to help spread the cool air from your energy-efficient air conditioner but don't forget to set the ceiling fans turning counter-clockwise in the summer! (When you stand underneath the fan, you should feel a breeze.)
• Install your energy-efficient air conditioner in a shady location, or in a window that gets little sun (typically on the north or east side of your home), for best operating results.
• Clean air conditioner filters regularly. If your filter looks worn or has holes, it should be replaced.
• Keep the front and back of the air conditioner unobstructed.
• Make sure your attic is properly ventilated, especially if you have good insulation.  Good ventilation can help reduce cooling costs by 10%.
