The Average Cost of an Air Conditioner Bill

National Average

• According to the White Fence Index, Americans pay about $250 per month for utilities as of 2011. Since the U.S. Energy Information Administration says that 8 percent of household energy use is due to air conditioning, it's likely that you spend $20 per month --- or $240 per year --- on air conditioning for your home. Various factors influence how much you actually spend.

Factors

• Your ability to tolerate hot weather determines how low you set your home's temperature. When it is significantly warmer outside than it is in your home, your air conditioner must work more, resulting in a higher utility bill. The size of your home also has an effect on your bill, since a larger home requires your air conditioner to circulate more cool air.

Additional Costs

• Central air conditioning units require filters, which the U.S. Department of Energy recommends you replace at least every two months. Debris such as dust and animal fur can decrease your air conditioner's efficiency by as much as 15 percent. Also, a broken air conditioner usually requires a professional to repair.

Alternatives

• Reduce your energy use by turning on your ceiling fan. It uses less than 3 percent of the energy required for central air conditioning, according to electricity expert Michael Bluejay, and makes you feel cooler by blowing air across your skin. With your fan on, you can set your thermostat to a higher temperature in warmer months and save money on your utility bill.
