Why does an air conditioner use so much electricity?

Radial Wave asked:


Before you classify this as a stupid question, think of this. The small motor that turns the fan at the top of the unit is maybe 2 amps and uses about 20 dollars worth of electricity in a month, if that much. However, the compressor makes my electric meter spin like a wild top out of control. Running the air conditioner makes my electric bill increase by roughly three hundred or more dollars each month — or more. By the way, my unit is only eight years old. Does anyone realize that true wealth and prosperity beyond imagination await the man that invents a genuine energy-saving compressor? So here is my real question : What the heck is in a compressor that sucks the electricity like a vampire? What could possibly be inside a compressor that uses so much juice?

    8 years is about the life of air conditioners, so it is going to be less efficient.

    TOO LATE
    The scroll type compressor saves energy, lasts longer, and is much quieter.

    Window units are designed to cool small areas, not usually the whole house. If the filter is noy cleaned or replaced on a rehular basis it has to weork harder. The harder is works the more energy it has to use. Plus if you have it running a an extreme low temp. it can’t stop. Try to find a comfortable setting and leave it there for a while. Besides, that is most likely NOT the only thing that is using ALL the electricity. Find ways to use less. Try using the “mini twist” flueresent bulbs the fit where regular light bulbs are used.

    8 years with 0 maintenance may cause the wild spinning in your electric meter. also, check your temperature settings. you setting might be higher than what you just need for comfort cooling. also, the thermostat may no longer we working. have it checked for efficiency - call your a/c technician.
