- The average consumer spends thousands of dollars a year on air conditioning and gas. Air conditioning can account for 40 percent of your utility bill. If you commute, you may need two or more tanks of gas a week to get to work. With electric bills and the price of gas on the rise, these factors only lead to higher costs, making saving on air conditioning and gas even more important.
Change Your Car's Air Filter
- A typical air filter needs to be replaced every 15,000 to 20,000 miles. A clogged air filter can cause a car to run inefficiently and waste gas. According to the Daily Green, replacing the air filter in your car can improve the car's gas mileage by up to 10 percent.
Have Your Car's Alignment Checked
- If your car's alignment is out of place, the engine will have to work harder and use more gasoline. Have your alignment checked by a licensed mechanic often, especially if you notice uneven wear in the tires.
Properly Inflate Your Tires
- According to the Daily Green, driving on under-inflated tires can cause a fuel deficiency of 2.8 percent. Even tires in their best shape lose their inflation over time. Use a tire gauge to check the inflation of your tires often and inflate them if they get below the manufacturer's recommendation.
Lower or Raise Your Thermostat
- According to the California Energy Commission, you can save 5 to 20 percent of your home's utility usage by lowering or raising your thermostat at least 5 degrees. A thermostat can be set to 78 degrees in warmer months and 68 degrees in cooler months while still keeping the room comfortable.
Replace the Air Conditioner Filter
- Air conditioners use a filtering system to process the air. These air filters clog easily and need to be replaced once a month. Once an air filter clogs, the air conditioner must work harder, causing an increase in utility bills.
Have an HVAC Inspection
- If you notice a sudden, unexplainable increase in your air-conditioning bills, you may have a leak in your system. Have a licensed HVAC technician check your air-conditioner ducts for leaks. According to Smart Money, air-conditioning leaks can add up to 20 percent to your utility costs.
Turn the Air Conditioner Off
- According to Smart Money, running your air conditioner while you are not home could be costing you more than $100 a year. Turn the air conditioner off when you are leaving for more than two hours, or install a programmable thermostat. Programmable thermostats allow you to set the temperature in advance.
